Abstract
Phosphors made from inorganic oxides and activated with rare earth metals are usedin numerous practical contexts. These include cathode ray tubes, high-efficiency luminouslights, x-ray radiography screens, field emission display panels, and many more.Inorganic phosphor compounds come in a wide variety of forms and have a wide variety ofpracticalapplications. Because of their many advantageous characteristics, including highquantumefficiency, long persistence of the phosphorescence, good stability, and the fact thataluminate-based phosphor is an excellent host material for the lamp industry, aluminatephosphors havea promising future in practical applications. Divalent europium ion dopedsynthetic hexagonal alkaline earth aluminate is an effective luminescence material. Plasmadisplays, field emission displays, fluorescence lamps, etc. all make use of phosphors based onaluminates.Nanophosphors based on the silicates Ba3CaSi2O8 and NaCeSiO4 havebeen produced at 900 ℃using the sol-gel process and doped with Eu3+. Fouriertransform infrared analysis (FTIR), X-ray powder diffraction (XRD), and photoluminescence(PL) techniques were used to examine the bonding, crystalline structure, andphotoluminescence properties of the produced nanophosphors. Europium doped bariumcalcium silicate (Ba3CaSi2O8:Eu3+) and sodium cerium silicate (NaCeSiO4:Eu3+) phosphorsemitted a red glow when exposed to ultraviolet (UV) light. The excitation and emission spectrawere analysed to determine the luminescence parameters of the produced phosphor. Based onXRD analyses, we know that the produced minerals Ba3CaSi2O8:Eu3+ and NaCeSiO4:Eu3+have orthorhombic and cubic structures, respectively, and have sizes of 46.36 nm and 28.57nm. The crystallinity of the finished products was uncovered by XRD analysis. Vacuumfluorescent displays, cathode ray tubes (CRT), safety indicators, luminous paints, fabrics, etc.all benefit from the optoelectronic characterisation of produced phosphors.
