Abstract:- Europium ion-doped phosphors have garnered significant attention due to their potential applications in solid-state lighting, dosimetry,optoelectronics and display technologies. These phosphors are known for their ability to emit light in the red to orange spectrum, which is crucial for creating white light in LEDs. Eu+3 ion shows photoluminescence from 5D0 excited state to 7FJ term which is represented as 5D0 →7FJ. The luminescence of Eu3+ doped phosphors is influenced by factors such as europium concentration and site occupancy, which can affect the emission colour and efficiency. The structural and luminescent properties of Eu-doped phosphors can be optimized by co-doping with other elements.Moreover, the charge compensation effect of alkali metal ions in some phosphors leads to enhanced luminescence and thermal stability, indicating their potential for white-light-emitting diode applications. Our objective is to explore the development of Eu (III) doped phosphors for their colour tunability and thermal stability. Building on recent advancements, we highlight the research prospects of this phosphors.
