Luminescence Properties Of Pure CaSO4 Nanoparticles Produced By Co- Precipitation Method
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 exhibi...

| description | 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. |
