Results of studies of the luminescent properties of MgF2 ceramics and MgF2 ceramics doped with tungsten trioxide synthesized in air upon exposure to a pulsed electron beam are presented. The photo- and cathodoluminescence spectra and the photoluminescence excitation spectra have been studied at 300 K both in as-prepared samples and in the samples after high-temperature annealing in air. The presence of luminescent centers of two types has been discovered: the electron color centers with the parameters similar to those in the MgF2 crystal structure and the emitting centers of the W–O–Va impurity type. The formation of the additional MgO phase in the annealed ceramics is observed.

MgF 2光学陶瓷
给出了研究MgF 2陶瓷和掺有三氧化钨的MgF 2陶瓷在空气中暴露于脉冲电子束后的发光性能的研究结果。在制备的样品和空气中高温退火后的样品中,都在300 K下研究了光和阴极发光光谱以及光致发光激发光谱。已经发现存在两种类型的发光中心:具有与MgF 2晶体结构中的参数相似的参数的电子色中心和W–OV–V的杂质类型的发射中心。观察到在退火的陶瓷中形成了额外的MgO相。
