摘要

Solution combustion synthesis approach was used to create warm orange-red light-emitting (Ca0.5Bi3O(1−x)Sm3xP2O10 (x = 0.2 – 2.0 mol%)) nanomaterials. The structural evaluation using XRD investigation was accomplished to identify the phase determination. The nanophosphors were organized into a triclinic phase with a (P-1) space group. EDS (Energy dispersive spectroscopy) and SEM (scanning electron microscopy) were used to investigate the elemental composition and morphological behavior, respectively. Additionally, transmission electron microscopy (TEM) confirmed the creation of nanoparticles. By recording the emission spectra, photoluminescent (PL) examinations show the emission (orange) from the formed nano-scaled crystals, the peak via 4G5/2 → 6H7/2 transition at 602 nm. In addition, the optimum sample’s decay time, non-radiative rates, quantum efficiency, and band gap were calculated to be 0.4959 ms, 55.07 s−1, 69.41%, and 3.85 eV, correspondingly. Ultimately, their outstanding luminous performance was reflected by the chromatic parameters, which included color co-ordinates (0.5595, 0.4396), color purity (86.07%), and 1941 K CCT (color correlated temperature). The above outcomes of the synthesized nanophosphors as a beneficial agent in advanced optoelectronic and latent fingerprinting applications.
