Abstract

A novel Li₄Zn(PO₄)₂ phosphor compound was synthesized using the renowned combustion synthesis method. The crystal structure and morphology of as-prepared phosphors were carefully examined along with their emission and excitation behaviors and decay profiles. The presence of constituent elements was also confirmed by energy-dispersive X‑ray spectroscopy. Photoluminescence studies revealed a noteworthy relationship between the emission intensity and the concentration of dopant Sm³⁺. Synthesized phosphors exhibited a remarkably intense narrow-band orange-red emission, peak at 597 nm when excited at 401 nm. The average lifetime of phosphors was found to be 1.11 ms. Furthermore, the chromaticity (CIE-Commission Internationale de I’Eclairage) coordinates of phosphors were accurately positioned in the red region, suggesting their suitability for lighting and display applications that require red-emitting materials. Overall, this novel Li₄Zn(PO₄)₂ phosphor exhibited promising luminescent properties, making it a potential candidate for various applications in lighting, displays, and other optoelectronic devices.

掺杂 Sm3+ 的 Li4Zn(PO4)2 荧光粉的光致发光研究

采用燃烧合成法合成了一种新型Li4Zn(PO4)2荧光粉化合物。对制备的荧光粉的晶体结构和形貌进行了仔细的研究，并对其发射和激发行为以及衰减谱进行了研究。组成元素的存在也被能量色散X射线光谱证实。光致发光研究表明，Sm3+掺杂浓度与发射强度之间存在显著的关系。合成的荧光粉表现出强烈的窄波段橙红色发射，在401 nm处激发时在597 nm处达到峰值。发现荧光粉的平均寿命为1.11 ms。此外，荧光粉的色度（CIE-Commission Internationale de I’eclairage）坐标被准确地定位在红色区域，表明它们适合需要发红光材料的照明和显示应用。总的来说，这种新型的Li4Zn(PO4)2荧光粉表现出了很好的发光特性，使其成为照明、显示器和其他光电器件中各种应用的潜在候选材料。
