Abstract

A series of Li₃Ba₂Y₃(MoO₄)₈ phosphors, co-doped with Sm³⁺ and Eu³⁺, were successfully fabricated through a high-temperature solid-phase synthesis approach. An exhaustive analysis was undertaken, encompassing the purity of the powder phase, the crystalline structure, morphological characteristics, elemental distribution, luminescent behavior, thermal robustness, and electroluminescent properties. The phosphor has high activation energy (0.40 eV) and good thermal stability. The light emission spectra of light-emitting diode (LED) devices fabricated using commercially available 400 nm LED chips and Li₃Ba₂Y_2.82(MoO₄)₈:0.12Sm³⁺/0.06Eu³⁺ were highly overlapped with the absorption bands of P_R, P_FR phytochromes, and chlorophylls a and b. These results demonstrate the significant potential of Sm³⁺/Eu³⁺ co-doped Li₃Ba₂Y₃(MoO₄)₈ phosphors for plant growing applications.

Sm3+/Eu3+活化Li3Ba2Y3 (MoO4) 8荧光粉交替触发光谱特性对植物生长的调节

采用高温固相合成方法，成功制备了一系列Sm3+和Eu3+共掺杂的Li3Ba2Y3(MoO4)8荧光粉。进行了详尽的分析，包括粉末相的纯度，晶体结构，形态特征，元素分布，发光行为，热鲁棒性和电致发光性能。该荧光粉具有较高的活化能（0.40 eV）和良好的热稳定性。利用市产400 nm LED芯片和Li3Ba2Y2.82(MoO4)8:0.12Sm3+/0.06Eu3+制备的发光二极管（LED）器件的发光光谱与PR、PFR光敏色素、叶绿素a和b的吸收带高度重叠。这些结果表明Sm3+/Eu3+共掺杂Li3Ba2Y3(MoO4)8荧光粉在植物生长方面具有重要的应用潜力。
