In one application of the invention, a non-polar 30 The solution is hexane or octane. Colloidal quantum wells are precipitated; CdSe 4 core, CdS core, CdSe / CdS core / shell, CdSe / ZnS core / shell, CdSe / CdZnS core / shell, CdSe / CdTe core / crown, and CdSe / CdSeTe It can be either a core or a crown. In another application of the invention... Colloidal quantum wells can also be CuInS, AgInS, and CuAgInS. one of the colloidal quantum wells and non-polar hexane or octane 5 the liquid; the diameter of the container used, the number of lines in the desired sequence, and the essence arranged in ratios selected according to the line width parameters in the array A solution A is prepared by bringing them together.

It is being prepared. The invention involves the method of dropping (100) solutions A and B into a polar liquid. In the step of creating a nanoparticle array on the polar liquid surface (104), The prepared non-polar A solution is drawn into a syringe, and the syringe cap is closed. It is dropped into the middle of the polar liquid inside. The dropped solution is labeled A, polar. It forms a circular shape on the liquid and is less dense than the polar liquid. Because of its density, it remains on the liquid surface without mixing with polar liquids. It remains there. Then solution B is dropped exactly in the middle of the same container. B Colloidal quantum wells (nanoparticles) present in the solution A pushing the solution into colloidal quantum wells on the surface of a polar liquid Because it has the property of applying force, colloidal quantum in solution A The wells are pushed towards the edges of the container so that there are no gaps between them. 25 It is compressed into a ring shape. Then solution B is transferred to the polar liquid. When dropped, it diffuses between the colloidal quantum wells in solution A. and the colloidal quantum wells in the solution do not mix with each other. Inside the ring form created by solution A, a new ring form exists. It forms a pattern. Solution A and Solution B contain colloidal quantum wells 30 The dripping process is repeated sequentially, and colloidal quantum action is achieved on the polar liquid. The number of rings created thanks to the wells can be increased to the desired number and nested within each other. A pattern with a past ring-like appearance is obtained (Figure 2). The invention is one of In another application, solution A is drawn into two separate syringes, and the syringes are placed in the container. They are positioned opposite each other, close to the edges. Furthermore... Then, solution A is simultaneously dropped from syringes onto the polar liquid. 5 Next, solution B is added to syringes containing solution A, and B Solutions B and B are simultaneously dropped onto the polar liquid. polar liquid surface after being simultaneously dripped from different syringes Solution A is being pushed from the wall of the container towards the center of the container. Furthermore... Then solution A is poured back into the syringes, and 10 is applied to the surface of the polar liquid. Solutions A and B are added drop by drop to syringes, respectively, and then into the polar liquid. A linear binary pattern is obtained by dripping the solution (Figure 3). the order in which the colloidal quantum wells within it are dropped onto the polar liquid surface It is possible to obtain different self-arrangements by changing their positions, The patterns specified in the specification are not exhaustive. 15 In one application of the invention, the position and height of the syringe on the container are fixed. assuming the container diameter is fixed at d=58 mm, the self-alignment line Their widths can be calculated using equation number 1: ………….(1) In equation 1, the nth colloidal quantum well material is It is the concentration. i. It is the width of the line. It is the coefficient. Its unit is... The unit is mg / mL, and the unit is (mg*m) / mL. 25 The invention method (100) involves the discharge of the polar liquid from the container from the container. by creating a nanoparticle array on the polar liquid surface, the substrate Obtaining nanoparticles with different self-arrangements as a result of transferring them to the surface 6 In step (105), the polar liquid inside the container can be discharged through a liquid drain outlet or a Solutions A and B are discharged from the container using a pump. using different patterns created on the surface of the polar liquid inside the container patterns formed by liquid drainage onto the substrate surface submerged at the bottom of the container is transferred. Thus, the desired colloidal quantum well array is formed on it. 5 It is possible to obtain a suitable substrate. There are some things to consider when creating an interlocking ring pattern. There are several parameters. The first parameter is the drop height or syringe. It is the distance between the surface of diethylene glycol and the colloidal quantum. This height is the colloidal quantum 10 It affects the speed at which the diethylene glycol liquid strikes the surface of the wells. Second The parameter is the density of colloidal quantum wells. This parameter is the liquid. It directly affects the size of the circles formed on the surface. Accordingly, n. The width of the circle is the density of the (n+1)th colloidal quantum well solution. It depends. In addition, the position of the nth circle is also (n-1). colloidal quantum well 15 It depends on the density of the solution. Many studies have shown that colloidal quantum between the density of the well solution and the widths of the circles formed This shows that there is a linear relationship. The third important parameter is the constant. The volume of the droplet is considered to be the droplet size. However, the droplet height is also considered. This is another parameter that is considered constant in this study. The 20 created... The width of the circles can be in the micrometer range. However, micrometers In order to create circles of that magnitude, the process must be very precise. It needs to be done. However, on the order of millimeters. Obtaining apartments is quite easy. Some parameters to consider when creating a binary pattern. There are several options. The first is the drop height or the syringe needle. This is the distance between the diethylene glycol surface. During the patterning process, this The height must remain constant. Otherwise, the pattern dimensions will change. Undesirable differences may occur. The second parameter is the drop's 30. It is the volume. The volume of drops of both materials dropped from the syringes. 7 They must be equal to each other. Furthermore, in this type of patterning method, a linear pattern is used. To have a binary pattern with an interface, you need to fulfill 3 conditions. They must be brought. The first condition is to instill the drops from both syringes simultaneously. This, It makes the structure symmetrical and creates the line interface. The second condition, The drip points of the syringes must always be in the same place. 5 Any incorrect placement results in an asymmetrical structure. Third The condition is to optimize material density to create the desired structure. It is a requirement. For example, to create a linear interface, a host is needed. nanoparticle solution and the second nanoparticle solution material Their densities need to be specific enough to form a narrow line. 10 Therefore, in a system requiring such precision, the simultaneous movement of the droplets... Designing a circuit for the dripping process and avoiding manual operation is preferable. The invention method (100) allows for the use of colloidal quantum well solutions with polar Patterns formed on a liquid surface are substrates located within the polar liquid. The pattern is transferred to the surface via the liquid-liquid interface. No reaction is performed during creation and patterning. No specific temperature is required. Colloidal material is used when creating the pattern. surface tension phenomena and intermolecular forces in quantum wells It is used. 20 Based on these fundamental concepts, the subject of the invention is "Achieving a Nanoparticle Self-Sequence". It is possible to develop a wide variety of applications for the Method of Doing (100), The invention cannot be limited to the examples described here, but mainly to the claims. as stated. 25
