WebFeb 1, 2024 · High-power white LED/LD for solid-state lighting puts forward higher requirements for glass ceramic phosphor, for example, large absorption, high luminous efficacy (LE), high quantum yield (QY), and excellent color quality (e.g., high color index (CRI) and low correlated color temperature (CCT)). WebNoteworthy is that, intrinsic emission of Tb3+ ions is attributed to the effective energy transfer from the trapped exciton state of the double perovskite host to Tb3+ ions. Finally, mixing 30% Tb3+ alloyed Cs2Ag0.6Na0.4InCl6:Bi and Cs2NaInCl6:10%Sb phosphors, a series of double-perovskite-based white light-emitting diodes (WLEDs) are prepared.

WebFurther, as time goes the compact fluorescent lamps (CFLs) have been surpassed by the warm white LEDs. In the solid state lighting (SSL) devices (including LEDs), violet, blue, and green LEDs are based upon InGaN semiconductors, while the red and amber LEDs are based upon AlInGaP semiconductors (Phillips, 2007; Krames, 2007; Schubert, 2005).
WebSince the mid-1990s, phosphors have played a key role in emerging solid-state white-lighting technologies that are based on combining a III-nitride-based near-UV or blue solid-state light source with downconversion to longer wavelengths. Almost all widely used …
