摘要: Abstract A series of Pb2+-doped SrZrO3 phosphors with a varying Pb2+ concentration has been successfully synthesized using the sol-gel method. The structural, morphological, and luminescence properties along electron paramagnetic resonance (EPR) have investigated in details. structural analysis was carried out by recording X-ray diffraction (XRD) patterns, which confirms pure-phase formation phosphors. morphological study performed scanning microscope (SEM) that showed micron-sized particles irregular morphologies. photoluminescence excitation emission spectra were also recorded. intensity shows maximum at 360 nm pumped 278 nm for SrZrO3:Pb2+. optimized is 0.015 mol. Investigations un-doped doped phosphor technique. Pure exhibits an axially symmetric EPR line g || = 1.93 ⊥ = 1.99. These lines are ascribed to Zr3+ ion. Additional not observed
