Автоматизированный канал регистрации спектрально-кинетических характеристик ОСЛ в широкозонных материалах

Abstract

An automatized channel for measurements of the optically stimulated luminescence (OSL) in materials was developed for the Perkin Elmer LS 55 spectrometer. New possibilities of the instrument to research the OSL were demonstrated on the example of hexagonal boron nitride micropowder. Spectral and temporal dependencies investigations of the luminescence intensity were held under 660-nm laser stimulation in a continuous wave mode at the temperature range of RT – 250 °C for h-BN microcrystalline powder.
