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 4G5/2\(\to \)6H7/2 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, 4G5/2—6H7/2 has been found to be around 53%, suggesting it as a potential laser material in addition to its use for designing white LED phosphors.
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.
