A novel near white light emitting phosphor KSrYSi2O7:Dy3+: Synthesis, characterization and luminescence properties

Synthesis, photoluminescence, Judd–Ofelt analysis, and thermal stability studies of Dy3+-doped BaLa2ZnO5 phosphors for solid-state lighting applications

“…For the optimal doping concentration, these coordinates approximately match the National TV Standards Committee (NTSC) standards ( x = 0.333, y = 0.0333) and are in accord with the available literature. 8,19,32 These findings suggest that the as-synthesized phosphor materials can be suitable for the generation of UV-excited warm white light emission.…”

“…In addition, the dopant Dy 3+ ions also seem to be present throughout the sample's surface. 8 Photoluminescence study…”

“…During the next ten years, the DOE predicts that the traditional methods of illuminating our planet, which began with incandescent light bulbs and progressed to overhead fluorescent ones, may become outdated. 8 …”

“…During the next ten years, the DOE predicts that the traditional methods of illuminating our planet, which began with incandescent light bulbs and progressed to overhead uorescent ones, may become outdated. 8 Several elds of science and technology have undergone a tremendous transformation because of phosphor-based lighting technology. 9 For application in solid-state lighting systems, researchers are continuously studying various phosphor materials that are reliable, inexpensive, eco-friendly, have a longer lifespan, etc.…”

Ho3+‐doped BaGd2ZnO5 green‐emitting phosphor for solid‐state lighting: synthesis, characterization, and photoluminescence properties

“…Both images also confirmed the successful incorporation of doping ions (Ho 3+ ) in the synthesized phosphor. However, a slight change in colour was observed for all the ions in the images recorded after sputtering, which could be ascribed to the elimination of contamination that occurred during the sample mounting and handling process [34].…”
