通过将特定的 CaF2 颗粒分散到 PDMS 基质中，提出了一种基于折射率匹配的新型紫外透明可见光散射光谱材料。这种混合材料可用于开发紫外线带通滤光片，该滤光片在 260-280 nm 附近表现出高透射率，并且在紫外线区域具有更宽的带宽。此外，可以通过研磨、沉淀和离心分离制备具有更窄尺寸分布的微米CaF2颗粒，分散在PDMS基质中后显示出更窄的透射光谱带宽。
A novel UV transparent visible scattering spectroscopic material based on refractive index matching by dispersing specific CaF2 particles into the PDMS matrix was proposed. This hybrid material can be used to develop a UV bandpass filter that showed high transmittance around 260-280 nm and wider bandwidth in the UV region. Furthermore, micro-CaF2 particle size with narrower size distribution that can be fabricated by grinding, precipitation, and centrifugal separation, showed narrower bandwidth of transmittance spectra after dispersing in the PDMS matrix.
