Abstract

Na₅Gd_1−x(MoO₄)₄:xSm³⁺ (x = 0–0.12) phosphors were synthesized via a high-temperature solid-state technique. Comprehensive analysis was performed on the phase purity, crystal structure, luminescence behavior, and thermal stability of the phosphors. Under excitation at 405 nm, due to the ⁴G_5/2-⁶H_i (i = 5/2, 7/2, 9/2, and 11/2) transitions of Sm³⁺ ions, the phosphors emit relatively intense red light. Remarkably, at 150 °C, the integrated emission intensity of Na₅Gd_0.92(MoO₄)₄:0.08Sm³⁺ attains 96 % of its value at ambient temperature, demonstrating its excellent thermal stability. A LED light source is created using a commercial 405 nm LED chip and Na₅Gd_0.92(MoO₄)₄:0.08Sm³⁺ phosphor, emitting a vibrant red light. Its electroluminescence spectrum overlaps with the absorption peaks of plant chlorophyll a/b and the phytochrome P_R/P_FR spectra, indicating its potential for use in plant growth lighting applications.

Na5Gd(MoO4)4: Sm3+ -一种具有特殊热稳定性的红色钼酸盐荧光粉，用于植物生长照明

采用高温固相技术合成了Na5Gd1−x(MoO4)4:xSm3+ (x = 0-0.12)荧光粉。对荧光粉的相纯度、晶体结构、发光性能和热稳定性进行了综合分析。在405 nm激发下，由于Sm3+离子的4G5/2-6Hi （i = 5/ 2,7 / 2,9 /2和11/2）跃迁，荧光粉发出较强的红光。值得注意的是，在150℃时，Na5Gd0.92(MoO4)4:0.08Sm3+的综合发射强度达到了常温时的96%，表现出了优异的热稳定性。采用商用405 nm LED芯片和Na5Gd0.92(MoO4)4:0.08Sm3+荧光粉制成LED光源，发出明亮的红光。其电致发光光谱与植物叶绿素a/b的吸收峰和光敏色素PR/PFR光谱重叠，表明其在植物生长照明中的应用潜力。

期刊介绍： JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds. All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor). The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
