A remote color converter with a phosphor in silicone (PiS) structure was fabricated using CsPbBr3 perovskite nanocrystal embedded glass (PNEG) as a green phosphor. When the PNEG was pasted on a glass substrate and mounted on a blue LED, it showed enhanced thermal and photo stability compared with the bulk PNEG. The remote color converter was used to prepare a white LED, which had a wide color gamut of up to 130% of the National Television Standards Committee (NTSC) defined area with the addition of K2SiF6:Mn4+ (KSF:Mn4+) as a red phosphor. The feasibility of a flexible remote white color converter using ultra-thin glass (UTG) as a substrate was examined and discussed. [ABSTRACT FROM AUTHOR]

A complete inorganic quantum dot color converter for a white LED is achieved using silicate-based quantum-dot-embedded glasses (QDEGs). The white LED exhibits a high CRI of 90 and highly improved thermal stability up to 200 °C, demonstrating its robustness and practicality. The CdSe/CdS core/shell structure within the silicate glass is expected to enhance the colour converting efficiency. [ABSTRACT FROM AUTHOR]
