Abstract

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.
