摘要：

EU2+-doped SrBPO5 with stillwellite structure has been identified as a new luminescent system which shows intense photostimulated luminescence for UV and X-ray radiations. Various spectral features observed for the new system are very much similar to BaFBr : Eu2+, the extensively applied phosphor system in digital radiography. Apart from its potential for application, the unusually low wavelength Eu2+ emission observed has been explained by the absence of preferred orientation of d-orbital of Eu2+ as dictated by crystal chemistry of the system.
