Evaluating the Effects of Vanadium- infused CaBP Nanophosphors: Insights into structural Morphological and Photoluminescent studies

Abstract

Abstract Due to their potential for use in numerous applications, including displays, medical imaging, lighting, and fluorescent lamps, phosphor luminescent materials especially those activated with transition metal ions— intensive research has been conducted over the last decade on these topics. Present document describes a report on the solid-state reaction method has been used to prepare nanophosphors of Ca6BP5O20:xVO2+ (x=0.01,0.03 & 0.05 mol%) and to examine the effects of vanadyl doping on structural and morphological studies using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier transform infrared spectra (FT-IR), and photoluminescence. Both the undoped and vanadyl-doped Calcium Borophosphate (CaBP and CaBP:xVO2+) nanophosphors. According to structural characteristics, both vanadium-undoped and vanadium-doped Calcium Borophosphate (CaBP&CaBP: VO2+) nanophosphors revealed triclinic structure, and the average crystallite sizes changed from 29 nm to 22 nm with increasing vanadium doping levels. Morphological research revealed that the pictures were like particles. Tetrahedral borate groups stretching vibration modes are represented in the FT-IR spectra by bands in the range of 1085-820 cm-1, whereas trigonal planar groups are represented by bands in the range of 1378-1236 cm-1. With an excitation wavelength of 385 nm, both undoped and vanadyl-doped photoluminescence spectra show a visible exude peak at 534 nm. The chromaticity results indicate that the VO2+ -doped CaBP nanophosphors had chromaticity coordinates (x,y) of (x = 0.2149, y = 0.5607), (x = 0.2119, y = 0.4688), and (x = 0.2110, y = 0.4071), correspondingly, which were located in blue-green, green, and pale blue colour spaces. When the dopant concentration is increased from 0.01 to 0.05 mol%, the light emission characteristics change from pale blue to green. These findings showed that transition metal ion-doped phosphor materials are appropriate for use in display device applications.
