Preparation and Luminescence Properties of Ba_（2-x）B_2O_5：xSm~（3＋） Red-Emitting Phosphor
摘要
Abstract
The Ba2–xB2O5：xSm3＋ phosphors were synthesized via the high temperature solid state reactions.The effect of the doping quantity of Sm3＋ activator on the luminescence properties was investigated.The results indicate that the sample synthesized is a pure phase of Ba2B2O5.The main excitation peaks were located at 342 nm（6H5/2→4H9/2）,359 nm（6H5/2→4D3/2）,372 nm（6H5/2→6P7/2）,400 nm（6H5/2→4F7/2）,436 nm（6H5/2→4G9/2） and 450～510 nm（6H5/2→4I13/2,4I9/2,4I11/2,4G7/2）,respectively.The main emission was located at 550–575 nm（4G5/2→6H5/2）,580–620 nm（4G5/2→6H7/2） and 630～660 nm（4G5/2→6H9/2）.The most intense emission was excited at a wavelength of 400 nm.It was found that the luminescent intensity firstly increased and then decreased with increasing Sm3＋ content（x）.The luminescent intensity had the best value when Sm3＋ content x was 0.06.The concentration quenching mecha-nism was the electric dipole–electric quadrupole interaction in the phosphor.关键词
