摘要： This paper synthesizes the Sr$_{2}$SiO$_{4}$\,:\,Eu$^{2 + }$ phosphor by high temperature solid-state reaction. The emission spectrum of Sr$_{2}$SiO$_{4}$\,:\,Eu$^{2 + }$ shows two bands centred at 480 and 547\,nm, which agree well with the calculation values of emission spectrum, and the location of yellow emission of Sr$_{2}$SiO$_{4}$\,:\,Eu$^{2 + }$ is influenced by the Eu$^{2 + }$ concentration. The excitation spectrum for 547\,nm emission has two bands at 363 and 402\,nm. The emission spectrum of white light emitting diodes (w-LEDs) based on Sr$_{2}$SiO$_{4}$\,:\,Eu$^{2 + }$ phosphor + InGaN LED was investigated.
