Özet

Luminescent host materials which have LaB3O6 crystal structure were prepared and their structural and luminescent properties were analysed using the combustion method. Therefore, the measurements were performed at various temperatures. Phase impurity and optimum conditions were particularly determined at 900 degrees C for the host material prepared. Phase structures and morphological properties of the host material were analysed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). LaB3O6 was observed to have monoclinic crystal structure. Photoluminescence (PL) method was used to analyse its emission properties. Thermoluminescence (TL) glow curves were recorded; starting from room temperature (RT) up to 450 degrees C at a constant increasing heating rate of 1 degrees C/s using a Lexsyg smart TL/OSL reader.
