Abstract In this study, different diffusion agents have been employed for preparing optical diffusers. Compared with their properties, significant differences exist in UV-shielding, near infrared shielding, dispersion, light scattering, and etc. The characterization comparison can be found in the testing. As the result of UV shielding effect and infrared shielding properties, fillers that contain the CeO2 perform well in UV shielding as well as ZnO quantum dots, while fillers that contain γ-AlOOH show excellent near infrared shielding effect. Based on diffusion effect in vertical direction, optical diffusers prepared by ZnO-CeO2@polysiloxane and ZnO-Qds@polysiloxane can exceed the level of commercial diffuser. Besides, the diffuser prepared by ZnO-Qds@polsiloxane show lower dependence on incident angle and perform well in aging properties. Moreover, the microspheres prepared by hydrothermal method show the best dispersion. In addition, some fundamental mechanisms are summarized and analyzed, which is a guide for preparing optical diffusers. Hence, such diffusion agents can be considered as a simple comparison for selecting excellent multifunctional optical diffusers.

不同漫射图案的漫射体新漫射现象的光漫射机制

摘要 在这项研究中，不同的扩散剂已被用于制备光学扩散器。与它们的性能相比，在屏蔽紫外线、屏蔽近红外线、色散、光散射等方面存在显着差异。在测试中可以找到特性比较。由于紫外线屏蔽效果和红外线屏蔽性能，含有CeO2的填料在紫外线屏蔽方面表现良好，与ZnO量子点一样，而含有γ-AlOOH的填料则表现出优异的近红外屏蔽效果。基于垂直方向的扩散效应，由ZnO-CeO2@聚硅氧烷和ZnO-Qds@聚硅氧烷制备的光学扩散器可以超过商业扩散器的水平。此外，由ZnO-Qds@pol硅氧烷制备的扩散器对入射角的依赖性较低，并且具有良好的老化性能。此外，水热法制备的微球表现出最好的分散性。此外，还总结和分析了一些基本机理，为制备光扩散器提供指导。因此，这种扩散剂可以被认为是选择优秀多功能光学扩散器的简单比较。
