Tellurium is one of the least common elements on Earth. Most rocks contain an average of about 3arts per billion tellurium, making it rarer than the rare earth elements and eight times less abundant p than gold. Grains of native tellurium appear in rocks as a brittle, silvery-white material, but tellurium

Optical Properties of Tellurium and Selenium

The optical properties of tellurium and of trigonal and amorphous selenium have been investigated at wavelengths extending from the intrinsic absorption edge to about 152 microns using polarized radiation. The refractive indices of tellurium and trigonal selenium have been determined from 4 to 14 microns and from 9 to 23 microns, respectively.
