Abstract
Local cathodoluminescence spectroscopy has been suggested for the development of durable self-glowing crystals based on crystalline solid solutions (Y, Eu)PO4. Nonradioactive ions of Eu3+ in these crystals cause strong luminescence in the visible range, initiated by small admixture (less than 1 wt %) of α-radioactive 238Pu. The intensity of self-glowing depends on the Y: Eu ratio and the 238Pu content. The optimal Y: Eu ratio responsible for the most intensive luminescence has been identified. The principal features of cathodoluminescence emission in (Y, Eu)PO4 crystals of various chemical compositions are being discussed.
