Abstract

Judd–Ofelt analysis and photoluminescence study of akermanite-structured Sm³⁺ -doped Ca₂MgSi₂O₇ phosphor synthesized by combustion synthesis followed by a solid-state reaction process is presented. PXRD confirmed the tetragonal structure with the P-4 21 m (No.113) space group. SEM, EDS, and elemental mapping confirmed the morphology and composition. The photoluminescence (PL) emission spectra indicate that the phosphor gives orange-red emissions at 603 nm attributed to ⁴G_5/2 \(\to \) ⁶H_7/2 transition. Optimum concentration has been found to be 0.4 mol%. The CIE chromaticity coordinates are 0.57, 0.43. The branching ratio with respect to the transition, ⁴G_5/2—⁶H_7/2 has been found to be around 53%, suggesting it as a potential laser material in addition to its use for designing white LED phosphors.

Ca2MgSi2O7 中的 Judd-Ofelt 分析和光致发光：Sm3+ 磷光体

本文介绍了通过燃烧合成法和固态反应法合成的掺杂 Sm3+ 的 Ca2MgSi2O7 磷光体的 Judd-Ofelt 分析和光致发光研究。PXRD 证实其为四方结构，空间群为 P-4 21 m（No.113）。扫描电子显微镜（SEM）、电致发光（EDS）和元素图谱证实了其形态和组成。光致发光（PL）发射光谱表明，荧光粉在 603 纳米波长处发出橙红色的光，归因于 4G5/2 \(\to \) 6H7/2 转变。最佳浓度为 0.4 摩尔%。CIE 色度坐标为 0.57、0.43。与 4G5/2-6H7/2 转变有关的分支率约为 53%，这表明它除了可用于设计白光 LED 荧光粉外，还是一种潜在的激光材料。

期刊介绍： The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications. Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field. A journal of The Minerals, Metals & Materials Society.
