A Novel SrZr(PO4)2:Dy2O3 Solid Solution for Photoluminescence and Super Capacitor Applications
摘要
This study demonstrates the successful synthesis of SrZr(PO4)2:Dy2O3 solid solutions via solution combustion method, employing glycine as fuel. Powder X-ray diffraction (XRD) confirmed the crystal structure, while scanning electron microscopy (SEM) provided detailed insights into the surface morphology. Fourier transform infrared (FT-IR) spectroscopy identified the functional groups present, further revealing the material's composition. Photoluminescence (PL) measurements reveal excitation bands at 350, 365, 390, 425, and 450 nm; emission bands at 480, 580, and 665 nm. Emission color of the sample plot in the CIE x,y co-ordinates reveal white emission close to the standard white (0.33,0.33) demanded by the international television committee. Finally, dielectric studies revealed promising potential for long-term energy storage applications, particularly in super-capacitors.
