摘要: Abstract The present paper reports synthesis and characterization of trivalent europium (Eu 3+ ) doped zirconium dioxide (ZrO 2 nanophosphors. Effect variable concentrations on photoluminescence (PL) thermoluminescence (TL) behavior is also studied. Samples were prepared by the combustion technique which suitable for less time taking techniques large scale production Starting materials used sample preparation are Zr(NO 3 Eu(NO urea as a fuel. was characterized an X-ray diffraction (XRD) with Eu (0.5–2.5 mol%). There no phase change found increase in concentration . Sample shows monoclinic structure crystallite sizes calculated Scherer׳s formula. surface morphology phosphor determined field emission gun scanning electron microscopy technique. Good connectivity grains sphere line FEGSEM. Functional group analysis Fourier transform infrared spectroscopic techniques. All phosphors (0.5–2.5 mol%) studied it that excitation spectra showed sharp peak centered at 295 nm. show strong peaks 594 nm 612 nm range dominant due to allowed electronic transition 5 D 0 → 7 F weaker magnetic dipole 1 Spectrophotometric determinations evaluated Commission Internationale de I׳Eclairage examined For recording TL glow curve, every 2 mg irradiated UV 254 nm source, fixed heating rate 6.7 °C s −1 well resolved 170 °C 2 mol% Also effect exposure dose versus intensity plot linear response broaden high temperature more stability fading curve. response, phenomenon may be useful dosimetry application.
