Description

One investigated into LiF-O promising luminophore by means of the nanosecond resolution pulsed spectrometry. One measured the luminescence kinetic characteristics of the uranium and oxygen centres at the initiation and at the dying down under 300 K. One revealed two-stage nature of the uranium luminescence initiation at the excitation by a nanosecond electron pulse. One determined the nature of the effect of a dose of crystal pre-irradiation by a train of electron pulses on the luminescence efficiency of the activators

Abstract (Russian)

Методами импульсной спектрометрии с наносекундным разрешением исследован перспективный люминофор LiF-O. Измерены кинетические характеристики свечения урановых и кислородных центров на стадии разгорания и затухания при 300 K. Обнаружен двухстадийный характер разгорания уранового свечения при возбуждении импульсом электронов наносекундной длительности. Определен характер влияния дозы предварительного облучения кристалла серией импульсов электронов на эффективность свечения активаторов
