Abstract

The reflectance of vitreous and metallic selenium has been measured in the spectral region between 550 and 1500 Å. At the shorter wavelengths the metallic form is a very poor reflector, whereas the vitreous form has a reflectance comparable with that of glass.

Reflectivity ratios as a function of photon energy. Curves A, B, and C represent the ratio of vitreous to metallic selenium for three independently prepared pairs of samples. Curve E represents the ratio Pyrex to metallic selenium. Curve F represents the ratio for Pyrex to vitreous selenium. Curve D is calculated from the work of Kandare and represents the ratio of vitreous to metallic selenium. Data for Curves F, C, and E were taken from the same three samples.
