Abstract Double perovskite halides are attracting considerable attention due to their applications in solar cells and photovoltaics. It is observed that many (more than 20) publications top journals have associated spectral features emission the region at 460–470 nm with “pristine” materials. This leads not only false observations but also incorrect conclusions concerning transformation of dark into bright excitons or boosting self‐trapped exciton (STE) emission. The use phrase STE commented upon. Most commonly, spectra present correspond those antimonate (III) ion, Sb 3+ . should be interpreted terms s p – 2 orbital transitions rather excitonic transitions. compounds Cs NaRECl 6 (RE = Y, Gd) synthesized by two major methods, namely: evaporation hydrothermal syntheses, for various rare earth starting materials, order demonstrate effect antimony contamination. Contamination Mn 2+ ion found samples double susceptible attack moisture. study emphasizes need check sample synthesis purity carefully monitor integrity

All-inorganic halide double perovskites have attracted extensive attention as new luminescent materials owing to their high luminous efficiency and wide emission spectrum. In this work, blue-red bicolor Cs2NaGdCl6 (CNGC) perovskite nanocrystals doped with Sb3+/Ho3+ were prepared using a hydrothermal method. The incorporation of Sb3+ significantly enhanced the intrinsic “self-trapped excitons (STEs)” wide-band bright blue centered at 470 nm. On basis, different concentrations Ho3+ introduced achieve color tunable from red region, extremely quantum efficiencies 96.53% 92.17%, respectively. By use diverse methods, including spectroscopic analysis fluorescence lifetime, mechanism efficient luminescence related dopant was comprehensively explored. Results show that not only can enhance STEs CNGC but also has an activation effect on rare earth ion Ho3+, because it plays role bridge for two energy transfer channels between centers, details investigated. Thermal stabilities studied over temperature range 303–473 K good performances demonstrated fact PL intensities CNGC:1%Sb3+ CNGC:1%Sb3+/10%Ho3+ 423 75.1% 70.1% compared those 303 K, With CNGC:1%Sb3+/10Ho3+ used, UV light-emitting diode activated devices fabricated characterized. emissions suggest materials’ prominent potential in application plant lighting. Finally, white-light sole matrix, strategy tri-doping Tb3+ proposed based principle three primary colors. device fabrication CNGC:1%Sb3+/10%Ho3+/2.5%Tb3+ sample characterization processes prove its feasibility then provide valuable insights design Sb ion-doped lead-free toward easily which be applied various fields.
