Problems solved by technology

Tests have shown that due to the poor mutual permeability between the dry layer (gel-like) and the wet layer (sol-like), this method is easy to form an interface between the layers, especially for highly volatile Solvent, which scatters the transmitted light, thus produces anisotropy to the light, forms a large optical background signal, and reduces the processing of the optical signal and the performance of the optical switch

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. In order to more specifically illustrate the advantages of the present invention, various conditions and processes are used to prepare nonlinear optical organic thin films in the examples, and the test results are compared and analyzed.

[0024] The research of the present invention on the preparation of the optical functional thin film is mainly the preparation of the non-linear optical organic thin film, and the optical thin film is prepared by the method of sol-gel and repeated spin coating. The polymer doped host material is PMMA, the guest material is Ethyl Red, and the substrate is a 25.4×76.2mm, 1mm-1.2mm thick glass slide (Sailing Brand, No.7101), soaked in acetone for several hours and rinsed with deionized water and dried. The organic solvents are chloroform (boiling point 61.2° C.) and cyclohexanone (boiling point 154-156° C.) respectively.

Abstract

The invention relates to a method for making non-linear optical organic thin film and corresponding solution. The method comprises employing repeating rotary coating technology to coat the organic dye / organic base film collosol on base chip. The invention is characterized in that the boiling point of the adapted organic solution is between 100 and 250 centigrade. Cyclohexanone can be the best organic solution.

Description

technical field [0001] The invention relates to the field of preparation of optical thin films, in particular to a method for preparing nonlinear optical organic thin films and the solvent used. Background technique [0002] During the preparation of optical thin film samples, the requirements for their optical properties are very high, and the quality of thin film sample preparation is crucial to the preparation and research of photonics and optoelectronics functional materials. In recent years, the preparation of optical thin films by chemical methods represented by sol-gel (sol-gel) method has attracted more and more attention, and it has developed into a strong competitor of traditional physical method coating. This is mainly due to the following advantages of chemical coating: 1) The preparation process is at normal temperature and pressure; 2) The purity and optical quality of the film are high; 3) The coating equipment and preparation costs are low; 4) The coating pro...
