Present study deals with the effect of Sm3+ doping on crystal and optical behaviour of Sr3MgSi2O8. For these studies prepared phosphor was characterized by using X-ray powder diffraction and luminescence spectra by recording excitation and emissions spectra. Emission spectra have emission wave lengths centered at 490 nm and 545 nm. Effect of Sm3+ ion concentration shows dipole–dipole interaction was responsible for the quenching shown by phosphor. The thermoluminescence curves were used to define the ability of the trap to trapping the carriers for Sm3+ doped Sr3MgSi2O8 phosphor.

Sm3+ 掺杂 Sr3MgSi2O8 荧光粉的结构和热响应研究

目前的研究涉及 Sm3+ 掺杂对 Sr3MgSi2O8 晶体和光学行为的影响。对于这些研究，通过记录激发和发射光谱，使用 X 射线粉末衍射和发光光谱表征制备的磷光体。发射光谱的发射波长集中在 490 nm 和 545 nm。Sm3+ 离子浓度的影响表明偶极-偶极相互作用是磷光体显示猝灭的原因。热释光曲线用于定义陷阱捕获 Sm3+ 掺杂的 Sr3MgSi2O8 磷光体的载流子的能力。
