Ba 掺杂和烧结温度对 Sr4V2O9：Eu3＋（5％），Ba2＋（x％）光学性质的影响
Luminescent properties of Sr4 V2 O9：Eu3+ (5%),Ba2+ (x%) phosphors tuned by Ba doping and sintering temperature
摘要
Abstract
Eu3+ and Ba2+ co‐doped Sr4 V2 O9 samples prepared via a hydrothermal method and sintered were reported .The luminescence of phosphors induced by Ba doping and sintering temperature were investigated using photoluminescence spectra .The results indicated that the emission intensity increased with Ba2+ dopants greatly and decreased again after sintered . It indicated that the magnetic dipole transition of Eu3+ ions was low and disappear after sintered ,and the crystal field surrounding of Eu3+ ions was highly changed after sintered .关键词
