Summary: Urea assisted combustion methodology was used to fabricate orthorhombic symmetry type BaGd2ZnO5:Dy3+ nanocrystals with luminance of cool white-color light. The nanocrystals exhibited agglomerated particles with non-uniform shape and crystal-size of 30-40 nm. The quenching phenomenon occurred after the optimized amount of dopant (Dy3+) was examined to be x = 3 mol%. The quenching mechanism was determined to be non-radiative relaxations of energy via exchange-type interrelations, validated by Inokuti-Hirayama (I-H) and Dexter's theory. The fabricated nano-powders had two bands at 492 nm (bluish) and at 581 nm (yellowish), and the optimal powder had a band gap of 4.71 eV, a decay lifetime of 0.7049 ms, and a quantum efficiency of 93.9%. The white-light emanation, represented by the CIE color-parameters, showed congruence with standard coordinates of commercial LEDs and NTSE, demonstrating their potential for advanced illuminating devices.

Summary: In this study, highly photostable and novel Gd2TiO5(GT):Dy3+/Eu3+ nanophosphors were reported as single-component white emitting phosphors prepared by sol-gel route. Tunable white light emission was achieved by co-doping various concentrations of Eu3+ ions to the optimized GT:1.5Dy(3+) nanophosphors, showing an increased energy transfer efficiency with rising Eu(3+) ion content for co-doped GT nanophosphors. The results suggest that these GT:Dy3+/Eu3+ nanophosphors can serve as potential single-component white emitting phosphors for UV and/or NUV-based pc-WLEDs.

Summary: In recent years, quantum dots (QDs) have emerged as a powerful building block for liquid-crystal display (LCD) technology, particularly in the form of color enhancement films. However, the challenge remains to develop efficient and wide color gamut LEDs for backlighting purposes. This study presents QD-based white LEDs that exhibit a high external quantum efficiency (EQE) of 39.8% and a wide NTSC color gamut coverage of 133.3%. These LEDs utilize giant CdSe/CdS core/shell QDs for red-emitting spectral range and green-emitting CdZnSeS/ZnS alloyed core/shell QDs, resulting in high photoluminescence quantum yield (PLQY) and narrow full width at half maximum (FWHM) values. The incorporation of QDs in liquid matrix on blue LED chips for LCD TV backlighting improves image brightness and color vibrancy, showcasing the potential of QD-based white LEDs for next-generation display technology.

Summary: In this study, a series of Mn-doped CsPbCl3 perovskite nanocrystals (PNCs) were synthesized using a facile, one-step, polar-solvent-free sonochemical method. The structure, morphology, and temperature-dependent photoluminescence properties of the Mn-doped PNCs were investigated. The substitution of Pb2+ with Mn2+ in CsPbCl3 PNCs caused lattice contraction without altering the morphology and structure. The Mn-doped PNCs exhibited dual-wavelength photoluminescence profiles and increased photoluminescence quantum yield and decay lifetimes compared to pure CsPbCl3.

Summary: Compositional engineering of CsPbBr3 perovskite nanocrystals (PNCs) through Zn(ii) doping is an effective strategy to enhance their stability, defect passivation, and photoluminescence (PL) efficiency. Doping ZnBr2 gradually transforms CsPbBr3 into Cs4PbBr6 and introduces additional Br- ions, leading to the inhibition of surface defects and improvement of PL quantum yield. Experimental characterization techniques reveal that ZnBr2 doping suppresses nonradiative carrier trapping centers and generates shallow energy states, facilitating radiative recombination. The temperature-dependent studies demonstrate that temperature changes can influence radiative recombination and de-trapping processes.
