“…TL yield and intensities are used to evaluate the nature of luminescence centres and defect concentrations, respectively, in solid samples. [49] Figure 9 shows typical TL glow curves for the nanocrystalline Sr 2 CeO 4 prepared using different fuels and exposed to a constant γ-irradiation dose of $1 kGy from a 60 Co source. The glow curve peak shape differed for different fuel samples.…”

Despite great advancements in optical materials and luminescent hosts, selfluminescent blue-emitting phosphors are very limited. In this study we present the influence of fuels used in combustion synthesis on the photoluminescence and thermoluminescence (TL) characteristics of self-luminescent Sr 2 CeO 4 blue-emitting phosphors. Four different fuels, oxalyldihydrazide (ODH), sugar, glycine, and ethylenediaminetetraacetic acid, were used to synthesize Sr 2 CeO 4. Powder X-ray diffraction patterns showed that pure orthorhombic Sr 2 CeO 4 was formed only with the ODH fuel and the other fuels resulted in the formation of impurity phases. Excitation spectra showed peaks at $290 and 340 nm, corresponding to charge transfer bands from different O 2 À to Ce 4+ ions. The emission spectra showed an intense blueemitting band at 470 nm and the highest emission intensity was found for the sample prepared with ODH. Furthermore, TL glow curves for the γ-irradiated Sr 2 CeO 4 nanophosphor showed that ODH as fuel produced a more intense glow curve compared with other fuels investigated. TL glow curve analysis was carried out by calculating parameters such as activation energy, frequency factor, and order of kinetics. This study explores the importance and role of fuel in tuning the optical properties of phosphor hosts.
