|
Thermoluminecsence (TL) characteristics of pure CaSO4
nanoparticles produced by co-precipitation method are presented. The
formation of the nanoparticles was confirmed by X-ray diffraction
(XRD) and scanning electron microscope (SEM). TL glow curve of
this phosphor, exposed to gamma radiation exhibits five overlapping
glow peaks in the complex glow curve at 463, 470, 483, 498
and521(K) respectively, using a computerized glow curve
deconvolution procedure. A photoluminescence (PL) emission band at
393 nm was observed for the synthesized nanoparticles. Different
synthesis conditions were examined in order to achieve highest TL
sensitivity. The produced nanoparticles exhibit superior
thermoluminescent sensitivity compared to that of its bulk equivalent
