Ce3+/Tb3+/Sm3+ co-doped phosphate glasses were prepared by melt quenching method. The full colors including blue, green and reddish orange emitting were observed simultaneously in the photoluminescent spectra of the glasses at 377 nm excitation, and the combination of these three emitting allows the realization of white light emitting. The CIE chromaticity coordinate (x=0.339, y=0.331) of the emission from the glass is close to the standard white-light illumination (0.333, 0.333). Moreover, the tunable luminescent color and chromaticity parameters could be realized by varying the content of Tb4O7 dopant in the glass composition, which is promising fluorescent materials for white light emitting diodes applications.

White Light Emitting Diodes

AbstractCarbon neutrality, energy savings, and lighting costs and quality have always led to urgent demand for lighting technology innovation. White light-emitting diodes (WLEDs) based on a single emissive layer (SEL) fabricated by the solution method have been continuously researched in recent years; they are advantageous because they have a low cost and are ultrathin and flexible. Here, we reviewed the history and development of SEL–WLEDs over recent years to provide inspiration and promote their progress in lighting applications. We first introduced the emitters and analysed the advantages of these emitters in creating SEL–WLEDs and then reviewed some cases that involve the above emitters, which were formed via vacuum thermal evaporation or solution processes. Some notable developments that deserve attention are highlighted in this review due to their potential use in SEL–WLEDs, such as perovskite materials. Finally, we looked at future development trends of SEL–WLEDs and proposed potential research directions.
