微乳液法合成的Eu3+掺杂La2（MoO4）3材料及其发光性能
Preparation of La2 (MoO4) 3 by A Simple Microemulsion Method and Its Photoluminescence Properties
摘要
Abstract
La2 ( MoO4 ) 3 micro-materials with different morphologies were prepared by microemulsion reaction of sodium molybdate (Na2MoO4·2H2O) and lanthanum nitrate(La(NO3)3·6H2O) un-der the help of micro emulsion system. The morphology of La2 ( MoO4 ) 3 samples gradually transform from oval shape to close spherical shape with the concentration of the surfactant of CTAB increasing from 0.2 mol/L to 0.4 mol/L. Under 396 nm excitation, La2(MoO4)3∶Eu3+samples calcined at 800 ℃ for 4 h emit 617 nm red light due to the forced electric dipole transition of 5 D0→7 F2 . The emission is strongest when the mole fraction of Eu3+ is up to 20%.关键词
