采用高温固相法合成了系列YBO3:Pr3+和Y3BO6 :Pr3+荧光粉。用XRD、SEM、激发和发射光谱对样品进行了表征分析。结果表明:硼源的用量决定了最终产物的相结构,样品呈现不规则的颗粒状。在紫外激发下,Y3BO6:Pr3+荧光粉展现了强烈的红色发光(1D23H4),而与3P0相关的蓝绿光发射发生猝灭。YBO3:Pr3+荧光粉的强发光区分布在紫外区(250~330 nm),在可见光区发光较弱,主要发光来自3P0能级。发光机理分析表明由于Y3BO6比YBO3具有更高的声子能量,因此在可见光区,Y3BO61D2发光为主,3P0部分发生淬灭,而在YBO3中可观察到3P0→基态跃迁发光。
A series of Pr3+ doped YBO3 and Y3BO6 phosphors were prepared via solid-state reaction. XRD, SEM, PLE and PL spectra were used to characterize samples. The results revealed that the dosage of B plays an important role in the formation of the final product and the samples were irregular and granular. Under UV excitation, Y3BO6:Pr3+ phosphors showed strong red luminescence (1D23H4), while the blue-green emission from 3P0 was quenched. The strong luminescence region of YBO3:Pr3+ is distributed in the ultraviolet region (250 - 330 nm). In the visible region, the luminescence from the 3P0 level is weak. The analysis of luminescence mechanism shows that because Y3BO6 has higher phonon energy than YBO3, Y3BO6:Pr3+ is dominated by 1D2 luminescence in the visible region, and the luminescence from the 3P0 level is quenched, while the luminescence from the 3P0 to ground state can be observed in YBO3.
