Embodiment 1

[0007] First prepare 100ml of micellar aqueous solution containing 0.06M trimethylhexadecylamine bromide, each take 20ml of the solution and put it into two containers of A and B respectively, and add 0.114g of cadmium chloride to the two containers of A and B respectively and 0.038g thioacetamide to prepare storage solution A containing 0.025M cadmium chloride and storage solution B containing 0.025M thioacetamide. Mix 2ml of storage solution A and 2ml of storage solution B with 0.2ml of cyclohexane, and vibrate under ultrasound for 10 minutes, then add about 1.25M sodium hydroxide 0.04ml drop by drop under the action of continuous ultrasound, and continue to Sonication for 10 minutes gave a yellow colloidal solution, and methanol was added to give a yellow precipitate. The precipitate was a mixture of single-armed and multi-armed CdS nanorods with an average diameter of about 41 nm and an aspect ratio of about 8. The precipitated toluene solution glows blue under UV light. ...

Embodiment 2

[0009] First prepare 100ml of micellar aqueous solution containing 0.08M trimethylhexadecylamine bromide, each take 20ml of the solution and put it into two containers of A and B respectively, and add 0.114g of cadmium chloride to the two containers of A and B respectively and 0.038g thioacetamide to prepare storage solution A containing 0.025M cadmium chloride and storage solution B containing 0.025M thioacetamide. Mix 2ml of storage solution A and 2ml of storage solution B with 0.2ml of cyclohexane, and vibrate under ultrasonication for 10 minutes, then add about 1.25M sodium hydroxide 0.04ml dropwise under continued ultrasonication (it takes about 5 minutes ), after the addition was completed, the ultrasonication was continued for 10 minutes to obtain a yellow colloidal solution, and methanol was added to obtain a yellow precipitate. The precipitate was a mixture of single-armed and multi-armed CdS nanorods with an average diameter of about 45 nm and an aspect ratio of abou...

Embodiment 3

[0011] First prepare 100ml of micellar aqueous solution containing 0.08M trimethylhexadecylamine bromide, each take 20ml of the solution and put it into two containers of A and B respectively, and add 0.114g of cadmium chloride to the two containers of A and B respectively and 0.038g thioacetamide to prepare storage solution A containing 0.025M cadmium chloride and storage solution B containing 0.025M thioacetamide. Mix 2ml of storage solution A and 2ml of storage solution B with 0.3ml of cyclohexane, and vibrate under ultrasonication for 10 minutes, then add about 1.25M sodium hydroxide 0.04ml dropwise under continued ultrasonication (it takes about 5 minutes ), after the addition was completed, the ultrasonication was continued for 10 minutes to obtain a yellow colloidal solution, and methanol was added to obtain a yellow precipitate. The precipitate was a mixture of single-armed and multi-armed CdS nanorods with an average diameter of about 35 nm and an aspect ratio of abou...

Abstract

A process for synthesizing the cadmium sulfide nanorods which can emit blue light under irradiation of ultraviolet lamp includes sufficiently mixing cadmium chloride with thioacetamine in the aqueous solution of the micelles of amine trimethyl hexadecanebromide, dripping the solution of sodium hydroxide to make S ions released by thioacetamine and cadmium chloride take part in reaction to generate nuclei, and gradual growing to become nanorods.

Description

technical field [0001] The invention belongs to a method for synthesizing semiconductor nanorods by a template method. Background technique [0002] Recent studies have shown that nanomaterials have different properties from bulk materials, and these properties depend on the size and shape of nanomaterials. Therefore, the synthesis of nanomaterials with different shapes and sizes has become the focus of current research. One-dimensional semiconducting nanomaterials have attracted attention due to their potential application in the development of nanodevices. As an important semiconductor material, one-dimensional CdS nanomaterials can have important applications in the fields of solar cells, nonlinear optics, and optoelectronic devices. Nanomaterials with different shapes based on nanorods may have different uses in the development of nano-devices and in the field of catalysis, so they have attracted more and more attention. For example, A.P. Alivisatos' research group sy...
