OPTICAL GLASS, METHODS FOR PRODUCING SAME (EMBODIMENTS), AND FIBRE OPTIC LIGHT GUIDE

摘要

An optical glass is proposed which is capable of luminescence in a range of 1000-1700 nm when excited by radiation with a wavelength between 400 and 900 nm. The glass contains P205 and/or B203 as the main glass-forming component and subvalent bismuth as the source of luminescence. Methods for producing such glass and a fibre optic light guide containing such glass are also proposed.
