OPTICAL PROPERTIES OF MERCURY SULFIDE,
Abstract
An arrangement for studying the optical properties of microcrystals is described. The absorption and reflection spectra of synthetic mercury sulfide crystals were obtained in the characteristic absorption region. The absorption edge of alpha-HgS free of impurities was observed at 610-millimicrons. A 575-millimicron band was detected in the absorption spectrum and a 600-millimicron band in the reflection spectrum. A photograph was taken of the diffuse reflection spectrum of powdered mercury sulfide samples obtained by grinding single crystals. The width of the forbidden zone of alpha-HgS was determined from the diffuse reflection spectrum and is 2.10 ev. A study was made of the influence of iodine and copper impurities, in various concentrations, on the diffuse reflection spectrum of mercury sulfide. (Author)
