Local cathodoluminescence spectroscopy has been suggested for 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 visible range initiated by small admixture (less than 1 wt%) of alpha-radioactive 238Pu. The intensity of self-glowing depends on Y : Eu ratio and 238Pu content. Optimal Y : Eu ratio responsible for the most intensive luminescence was identified. Principal features of cathodoluminescence emission in (Y,Eu)PO4 crystals of various chemical compositions are being discussed.
