Refractive index boron
WebSep 15, 1995 · Optical properties of cubic boron nitride were studied in the spectral range from 400 to 50 000 cm−1. Raman-scattering, absorption, and reflection spectra were measured. The regions of the one-phonon and multiphonon absorption were studied in detail and the energies of the phonons were determined. WebMay 21, 2024 · The refractive index of AlN is 2.92 [10]; while the mean index of fully dense BN is 2.11 (see PBN). The refractive index of BIN77 is 2.53, and is therefore consistent with its composition of 50BN:50AlN (mol%) and 10% porosity. Grade PBN is a fully dense, high-purity, highly oriented material, so its refractive index values lie
