Abstract
At the realm of luminescence in the present period, phosphates are the fresh and developing candidates. In the suggested study work, citric acid is used as a fuel to create Sm3+- and Eu3+-activated/co-activated KSrPO4 phosphor by a simple combustion process. Through the use of XRD and Rietveld refinement, the phase identity and crystal structure of produced phosphor are examined. SEM is used to examine the morphological study, elemental analysis and elemental analysis of the sample together with the planned phosphor. The suggested phosphors’ vibrational properties were confirmed through the use of FTIR. The suggested phosphor’s charge compensation effect and photochromic qualities demonstrate three instantaneous emission peaks in the visible range, which results in the emission of white light. The produced phosphor is a viable option for white light-emitting diodes and display applications, as confirmed by all these findings.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
