These days, white light-emitting luminescents (WLELs) have garnered a lot of interest for use in displays, general lighting, and various electronic devices because of their superior mechanical durability, extended lifespan, and exceptional efficiency when compared to conventional incandescent and fluorescent lights. Nevertheless, there are a few significant flaws that are mostly related to phosphor and resin, including poor colour rendering capabilities, inhomogeneous spectrum distribution, and deterioration with heat and moisture. As a result, the development of phosphor-embedded glass-ceramics has emerged as a viable method for producing robust solid-state lighting fixtures. However, there is a higher chance of interactions happening between the glass host and the phosphor substance in these procedures. As a new generation of phosphor and/or epoxy-free white light sources, rare earth ion-doped luminescent glasses have attracted a lot of attention thus far because of their advantageous qualities, which include high thermal and chemical stability, high transparency, and a simple manufacturing process.Through down-shifting and up-conversion emissions, this review article seeks to provide a thorough summary of current developments in singly, doubly, and triply doped glasses with Rare Earth ions for solid-state lighting applications. Theoretical background is provided in depth, covering radiative and colorimetric characteristics, glass manufacturing techniques, and energy transmission processes. In order to improve the white light emission of luminescent glasses and expand their application areas, a number of efficient strategies are finally highlighted that minimise the significant challenges related to rare earths providing energy transfer from quantum dots or nanoparticles to lanthanides and doping lanthanides in low phonon energy glass.
