摘要：
Polycrystalline KZnSO4Cl : Eu and KMgSO4Cl : Eu prepared by a wet chemical method have been studied for their thermoluminescence (TL) and photoluminescence ( PL) characteristics. The PL emission spectra of the phosphor suggests the presence of Eu2+ and Eu3+ in the host compound occupying two different lattice sites. The TL glow curve of the KZnSO4Cl : Eu compounds has a simple structure with prominent peaks at 200 and 290 degrees C, while KMgSO4Cl : Eu peaks at 165 and 265 degrees C. The TL sensitivity of the phosphors is compared with CaSO4 : Dy and is found to be 3.4 and 2.4 times less in KZnSO4Cl : Eu and KMgSO4Cl : Eu phosphors, respectively.
