Paper Abstract

At present there is a great interest in phosphors producing high light yield in long wavelength region (550 - 1050 nm). They have a lot of application in different fields of physics such as laser physics, medical physics and tomography, semiconductor physics and others. The main reason of that is the emission spectra of these materials match well to sensitivity of silicon photodiodes. In this paper we present the spectral and decay time characteristics of some long-wavelength phosphors (such as AIIBVI, Al2O3:Ti, some molybdates, Gd2O2S and Y2O2S doped with Tb, and some others). The process of energy transfer to emission centers are considered. In most cases, types of the centers responsible for radiative transitions were determined.
