Understanding the role of fuels and impure phases on photoluminescence and thermoluminescence properties of combustion-derived nano Sr CeO blue light-emitting phosphor.

Despite great advancements in optical materials and luminescent hosts, self-luminescent 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 CeO blue-emitting phosphors. Four different fuels, oxalyldihydrazide (ODH), sugar, glycine, and ethylenediaminetetraacetic acid, were used to synthesize Sr CeO Powder X-ray diffraction patterns showed that pure orthorhombic Sr CeO was formed only with the ODH fuel and the other fuels resulted in the formation of impurity phases.
