摘要

This paper reports the photoluminescence and afterglow of Sr₂SiO₄ doped with Eup>2+p> and Dyp>3+p>. Factors governing the formation of the monoclinic or orthorhombic phase of this ortho-silicate are described and the impact of the crystallographic modification on the luminescence and afterglow under UV and VUV excitation are discussed and insight in factors limiting the efficiency of this yellow afterglow material is given.
