Phase recognition, structural measurements and photoluminescence studies of reddish-orange-emissive YAlO3:Sm3+ perovskite nanophosphors for NUV energized WLEDs

Combustion derived single phase Y4Al2O9:Tb3+ nanophosphor: crystal chemistry and optical analysis for solid state lighting applications

“…48 The bands present at 716 cm −1 and 791 cm −1 are assigned to Y-O bonds. 49 The results of FTIR study fairly corroborate with the XRD analysis data.…”

Crystallographic, morphological and photoluminescent investigations of Tb3+‐doped YAlO3 perovskites for lighting applications

“…From the earlier times, material innovators have made efforts to replace traditional lighting tools with solid‐state lighting devices possessing advanced light‐emitting properties [3, 4]. Therefore, rare‐earth (RE) doped light harvesting nanomaterials are the important constituents as they can be used in display units [5, 6], fluorescent lamps [7], amplifiers and lasers [8], white light‐emitting devices (WLED) [9, 10] or nanophosphors [11, 12] due to a broad spectral response from the UV to the infrared regions. Characteristic luminescence of phosphors primarily depends on the types of host lattice, synthetic method, nature and the concentration of the dopant ion [13].…”

Gadolinium-based Sm3+ activated GdSr2AlO5 nanophosphor: synthesis, crystallographic and opto-electronic analysis for warm wLEDs

“…So, in RE family, Sm 3+ ion having the usual f-f electronic-transitions are commonly used as effective dopant for orange/red visible light in host matrix. 27 To investigate novel red nanophosphor modules for wLEDs, further more research on Sm 3+ doped inorganic material has been dynamically launched. Largely, the classic solid-state reaction (SSR) technique is typically used to develop nanophosphor.…”
