A cyan-emitting phosphor Ca3SiO4(Cl,Br)2:Eu2+ with high efficiency and good thermal stability for full-visible-spectrum LED lighting

Rare‐Earth‐Based Perovskite Cs2AgScCl6:Bi for Strong Full Visible Spectrum Emission

“…Recently, the technology of full-spectrum health lighting is constantly improving, as well as the market scale is expanding. [15][16][17] Therefore the research and development of mono-component material with high color rendering white emission have been a research hotspot of lighting. [11,18,19] For the well-known quantum dots, perovskite nanocrystals (NCs), organic-inorganic perovskites, and rare-earth (RE)-based materials, all of them have excellent optical performance with the emission from quantum effect, free exciton (FE), self-trapped exciton (STE), and RE ions, and these materials can hardly achieve full spectra luminescence alone.…”

Efficient violet-light-excitable blue-cyan phosphor for full-spectrum lighting

“…5,6 Nowadays, compared with the most used (Ga,In)N blue chips, near-ultraviolet (N-UV) chips can produce pc-WLED devices with a higher color rendering index (CRI), lower correlated color temperature (CCT) and wider color gamut using RGB (red, green and blue) phosphors. [7][8][9][10][11] However, it is worth noting that the wavelength of visible light starts from 380 nm and the human eye is most sensitive to green light. 12 The invisible N-UV light at 365 nm is useless for full-spectrum lighting and harmful to the human body.…”

Phase-sensitive radioluminescence and photoluminescence features in Tm3+-doped yttrium tantalates for cyan and white light generation

“…19 The second strategy is to fabricate a near-ultraviolet (UV, 200 to 410 nm) LED chip with tricolor (a combination of blue, green, and red) emitting phosphors. Considering that UV LED can offer a more efficient solid-state light, 20 further attention has been paid to the design of new phosphors that can be excited in the UV range, 17,18,21,22 due to the urgent need for highly efficient white light-emitting solidstate devices. 15 The current phosphor materials exploited for solid-state lighting based on UV InGaN LEDs are BaMgAl 10 O 17 : Eu 2+ for blue emission, ZnS:Cu + ,Al 3+ for green emission, and Y 2 O 2 S:Eu 3+ for red emission.…”

“…38 Therefore, it is of great significance to explore new and original cyan phosphors for improving the quality of white light. 21 Here, we explore a tunable blue to cyan emission and an intense white-light emission in a unique Tm 3+ -doped YTO phosphor prepared by a versatile, non-temperature synthetic route based on the sol-gel method. We have conducted a structural, vibrational and spectroscopic study as a function of the annealing temperature to investigate its effect on the crystalline polymorphs Y 3 TaO 7 and M′-YTaO 4 and their correlation with the photoluminescence properties.…”
