Description

Pulsed cathodoluminescence (PCL) of CeF3 crystals was studied, the results are presented. PCL was excited by bombarding samples in the air at room temperature using a 170 keV pulsed electron beam of 2-ns duration, current density of 160 A/cm2, and repetition rate of 2.5 Hz. Luminescence and phosphorescence were observed in the UV and visible spectral regions. The phosphorescence is tentatively associated with the Ce2+ ion formation

Abstract (Russian)

Приводятся результаты исследования импульсной катодолюминесценции (ИКЛ) кристаллов CeF3. ИКЛ возбуждалась при облучении образцов в воздухе при комнатной температуре электронным пучком длительностью 2 нс при энергии электронов 170 кэВ, плотности тока 160 А/см2 и частоте следования 2.5 Гц. Обнаружены люминесценция и фосфоресценция в ультрафиолетовой и видимой области спектра. Предполагается, что фосфоресценция связана с образованием ионов Се2+
