【摘要】This paper synthesizes the Sr2SiO4:Eu2+ phosphor by high temperature

solid-state

reaction.The

emission

spectrum

of

Sr2SiO4 :Eu2+ 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 Sr2SiO4 : Eu2+ is influenced by the Eu2+ 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 Sr2SiO4 : Eu2+ phosphor + InGaN LED was investigated. 【总页数】3页(1135-1137)
