Analyzing Potential Minerals of REE in Nepal and Computational and Experimental Study of YAG-Ce Phosphor by Changing Dopant Composition and Calcination Temperature
Abstract
Rare earth elements (REEs) are used in a variety of contemporary high-tech products, which has raised their demand all over the world. It is highly probable that these elements will be obtained in Nepal, as this country is situated between China and India, two major producers of REE. The purpose of this study is to collect likely REE-containing rock minerals and coal samples from various places in Nepal in order to examine REE content and understand how different REEs exist in different samples. REEs from the collected minerals are extracted using recently developed green methods. Simultaneously, carry out theoretical modeling and experimental work to prepare Ce3+ ion-doped yttrium aluminum garnet (YAG- Ce) phosphor at varied levels of combing salts, fuel kinds, and calcination temperatures. The optical and electrical properties of the laboratory-synthesized YAG- Ce product will be characterized with different instrumental techniques such as XRD, SEM, EDS, and so on. The solution combustion method will be used to prepare YAG- Ce phosphor, as it provides for homogeneous dopant distribution throughout the crystal lattice and is considered the best option for enhancing phosphor quality. The application of the phosphor can be expanded by decreasing the particle size and improving crystallinity. It can be accomplished by altering the reaction conditions. In this project, graduate students will be recruited, and the results will be published in peer-reviewed journals. New-generation phosphors with wider application and better performance are the key ideas of this project. This research will explore additional REE resources and may uncover Nepal s REE production potential, which will help to maintain a worldwide supply chain network. It may also boost the national economy. Many new research topics will emerge that employ REEs as the key starting materials and help build the capacity of academia.
