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.

Comparison between selenium and tellurium clusters ...

Selenium and tellurium clusters are produced by the inert gas condensation technique. The mass spectra of both species are completely different and reveal different properties. In selenium, a periodicity of 6–7 is observed and may be interpreted by the binding energy between small cyclic molecules. Moreover, it was very difficult to obtained large clusters probably because the binding energy ...
