OPTICAL PROPERTIES OF THE Ag28Ga28Ge532Er2S1123 AND Ag12Ga12Ge228Er2S483 GLASSES
Journal Title: Фотоэлекторника - Year 2018, Vol 27, Issue
Abstract
Absorption spectra of the glasses Ag28Ga28Ge532Er2S1123 and Ag12Ga12Ge228Er2S483 in the 450–1050 nm range at room temperature were investigated. PL bands with maxima at 980 and 1540 nm were recorded under laser excitation with 800 nm wavelength. PL emission mechanism is analyzed from energy transfer processes, taking into account partial cluster formation of erbium ions and energy transition diagram of Er3+.
