A novel Mn<sup>4+</sup>-doped double-perovskite red phosphor K<sub>2</sub>NaScF<sub>6</sub>:Mn<sup>4+</sup> with ultra-high synthetic yield and uniform spherical morphology was developed for ultra-wide color gamut LCDs.
Oxidation of amines to imines under light irradiation has been widely studied in the field heterogeneous catalysis. For first time, we demonstrate a facile mixing calcination approach for preparation CeO2/g-C3N4-x as heterojunction catalyst photo-oxidative coupling benzylamine 300 W Xe arc lamp at 308 K with air balloon. It was found that rate constant CeR/CN-66% 3 times high pure CeO2 or g-C3N4. All kinds structural characterizations suggested formation between and g-C3N4, serving tunnel...
To improve absorption efficiency (AE) and subsequently external quantum (EQE) remains one of the significant challenges for Mn4+-doped red-emitting fluoride phosphors. In this study, we propose to use Mn4+ as a part matrix enhance AE Red-emission phosphors Cs2MnF6, Cs2MnF6:Sc3+, Cs2MnF6:Si4+ were synthesized successfully by coprecipitation method. The Rietveld refinement X-ray diffraction reveals that red phosphor exhibits cubic structure in Fm3̅m space group. Owing being matrix, kind...
Abstract Fluoride phosphors as red components for warm white LEDs have attracted a tremendous amount of research attention. But these are extremely sensitive to moisture, which seriously limits their practical industrial applications. To tackle this problem, unlike all the straightforward preventive strategies, reverse strategy “Good comes from bad” was successfully developed treat degraded K 2 SiF 6 : Mn 4+ (D‐KSFM) phosphor in present study, not only completely restores luminescence...
A novel Sr2MgB2O6 (SMBO) green-emitting phosphor co-doped with Ce3+-Tb3+ was synthesized at 950 °C via solid-state reactions, and the ultra-narrow-band green emission of Tb3+ significantly enhanced almost 20 times energy transfer from Ce3+ to Tb3+. It found have a broad excitation band (250 400 nm), full width half-maximum (FWHM) dominant around 544 nm only about 10 nm. The electronic gap SMBO matrix calculated by density functional theory (DFT) be 4.60 eV, this well verified diffuse...
Abstract In this study, Cr 3+ ‐doped and Mn 4+ ‐Cr co‐doped double perovskite fluoride phosphors K 2 LiGaF 6 are prepared using a simple hydrothermal method. High‐efficiency near‐infrared (NIR) emission near 762 nm is obtained under blue‐light excitation, the co‐doping effect of on NIR luminescence properties studied. Compared with single‐doped phosphor, , exhibit sharp increase 129% in emission, an enhancement internal quantum efficiency from 82.5% to 90.0%, thermal stability at 425 85.0%...
Abstract Y 1.94 MAl 4 SiO 12 :0.06Ce 3+ (M = Ba, Sr, Ca, Mg) phosphors were successfully prepared through a classic solid‐state reaction method. The crystal structures, photoluminescence spectra, quantum yields, and thermal stabilities of the investigated in detail. results indicate that all maintain structure garnets. emission peaks are located at 537, 538, 554, 565 nm, respectively. A red‐shift trend peak is observed with decreasing M radius, which can be ascribed to increase crystal‐field...
