  • Abstract
    در اين مقاله ويژگي هاي ترمولومينسانسي نانوذرات خالص CaSO4 مورد بررسي قرار گرفت. نانودرات CaSO4 بوسيله ي روش همرسوبي سنتز شدند. محصول به دست آمده بوسيله ي روش هاي مختلف مانند پراش اشعه ايكس (XRD) ، ميكروسكوپي الكتروني روبشي (SEM) مورد بررسي قرار گرفت. منحني تابش ترمولومينسانسي نشان داد كه محصول داراي 5 پيك همپواني شده در 463، 470، 483، 498 و 591 كلوين مي باشد. نانوذره ي سنتز شده داراي نشر فوتولومينسانسي در 393 نانومتر مي باشد. در اين مقاله همچنين از شرايط مختلف در سنتز استفاده شد تا محصول به ويژگي هاي ترمولومينسانسي بهينه برسد.
  • Abstract
    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.
