Luminescence Spectroscopic Investigation of Eu³⁺ Doped Oxides: Review

Abstract

Given their potential utility in a variety of fields, including solid-state lighting, flat-panel displays, solar energy converters, optical amplifiers, and more, phosphors and glasses driven by Rare Earth (RE) ions and emitting multiple colors have attracted a lot of interest. Full-spectrum lighting, high-efficiency near-infrared emission, and wide colour gamut display are the primary difficulties for these emerging RE doped phosphors, which are dependent on the emission characteristics of the phosphors utilized. The various methods of synthesis for Eu3+ activated red emitting phosphors are discussed, with an emphasis on the aspects that contribute to improved luminous performance. This luminescence analysis is used in investing the Crystal structure and defects in metal oxides from which it provides information on the chemical and mechanical behavior of metal oxides during mining and processing operations. In this description, we outline the research findings and talk about the luminescence theory of the Eu3+ doped glasses and oxides for the red emission.
