Synthesis and Luminescent Properties of Single-phase White Light-emitting Ba_（1.3）Ca_（0.7）SiO_4 Phosphors
摘要
Abstract
Single-phase white light-emitting Ba1.3Ca0.65–xSiO4：0.02Eu2＋,0.03 Mn2＋,xRe3＋（Re = Tb,Er;x = 0–0.04） phosphors were synthesized by high-temperature solid-state reaction.Luminescence properties of the phosphors and influence of various ratios of Re3＋ on spectral properties were investigated.Results show that these phosphors can be well excited at 340–415 nm,matching with InGaN-chip（350–410 nm）.Emission spectra consist of blue–green light of 425–560 nm and orange-red light of 560–680 nm,attributed to 5d→4f transition of Eu2＋ and 4T1→6A1 transition of Mn2＋,respectively.Doping of Tb and Er could effectively enhance the luminescence intensity of the system,and the luminescence intensity of Tb-doped phosphor is higher than that of Er-doped.Color emission of all prepared samples is located in white light color areas,color temperature among 3 900–5 000 K,color rendering index above 78.关键词
