Optimized tellurite glasses containing CsPbBr3-quantum dots for white-light emitting diodes

Spectral Tuning, Stabilities under External Exposures, and Spontaneous Enhancement of Emission Intensity in Grown‐into‐Glass All‐Inorganic Metal Halide Perovskite Nanocrystals

“…Normally, artificial white light is realized by additively mixing the emissions from red, green, and blue (i.e., tricolors) LED chips or by combining multiple color-emitting or single white-emitting materials with a UV/blue LED chip or laser. [5,[56][57][58]66,69,70,89,98,99,103,104] The most desirable white light should feature low risk (e.g., no serious UV light leakage), high CRI and low CCT values, as well as an emitted white light perception as close as possible to natural sunlight (i.e., warm white). Following these guidelines, we have designed a prototype by a direct blend of the light from a 405 nm laser, green light from GIG-CsPbBr 3 powders (i.e., not monolithic glass), yellow light from commercial YAG:Ce 3+ phosphor, and red light from the CaWO 4 :Eu 3+ phosphor.…”

Precipitation of cesium lead halide perovskite nanocrystals in glasses based on liquid phase separation

“…In most cases, CsPbX 3 PNCs are in situ precipitated in glasses through melt-quenching and subsequent thermal treatment. [30][31][32][33][34][35][36][37][38] Due to the inert and dense structure, glass provides good protection of these PNCs from the harsh environment and guarantee the stability against heat, moisture, and light irradiation. 30 In addition, precipitation of CsPbX 3 PNCs into glasses can also take advantages of the processing ability of glass, which makes it possible to shape the CsPbX 3 PNCs embedded materials into various forms including powders, fibers, plates, thin films, and waveguides.…”

After the pioneering work by Ai et al, CsPbX 3 PNCs have been successfully precipitated in borosilicate glass, 31,32 borogermanate glass, 33,34 borophosphate glass, 30,35 tellurite glasses, 36,37 oxyfluoride glasses, 38 and chalcogenide glasses. 39 Potential applications of these CsPbX 3 PNCs embedded glasses such as lightemitting diodes, 33,36,37 anticounterfeitings, 40 data storage media, 41 scintillators, 42 color filters, 43 and undersea water communications 44 have been demonstrated.…”

“…In recent years, CsPbX 3 PNCs embedded glasses have attracted a lot of attention. In most cases, CsPbX 3 PNCs are in situ precipitated in glasses through melt‐quenching and subsequent thermal treatment 30–38 . Due to the inert and dense structure, glass provides good protection of these PNCs from the harsh environment and guarantee the stability against heat, moisture, and light irradiation 30 .…”
