Optical Properties of Potassium Erbium Double Tungstate KEr(WO4)2

Abstract

Results of spectroscopic investigations of crystalline potassium-erbium double tungstate KEr(WO4)2 are reported. The single crystals of KEr(WO4)2 were grown by Top Seeded Solution Growth (TSSG) technique. They belong to the chain layered group of materials crystallizing in monoclinic syngony (space group C(sup 6 sub 2h-C2/c). The investigations were carried out in the broad spectral and temperature range (temperature range from 1.1K up to room temperature and the spectral range from 6000/cm to 25000/cm). It was found that the potassium erbium double tungstate belong to the class of the diaxial crystals and it is a pleochroic. The main optical absorption spectra are determined.
