Synthesis and optical properties of novel Gd3+-doped BaZn2(PO4)2 glass-ceramics for radiation detection applications
文献摘要：
45P2O5-15BaO-25ZnO-15B2O3 glasses doped with different concentrations(0 mol％,0.1 mol％,0.25 mol％,0.5 mol％,and 0.75 mol％)of Gd3+were prepared by a melt-quenching method and treated to fabricate glass-ceramics containing BaZn2(PO4)2 crystals by controllable crystallization.The struc-tural,optical,and dosimetric properties were investigated.FTIR spectra indicate that the glasses are composed of[PO4],[BO3],and[BO4]basic structural units.The XRD pattern analysis indicates that the samples contain BaZn2(PO4)2 crystals.In the photoluminescence(PL)spectra,two emission bands are observed at 307 and 313 nm due to the 6P5/2→857/2 and 6P7/2→8S7/2 transitions of Gd3+,respectively.The OSL dosimetric properties of glass-ceramics were studied further under beta radiation of 90Sr.The optimal Gd3+doping concentration of 0.5 mol％was determined.The fading of the OSL signal shows that the CW-OSL signal of Gd3+-doped BaZn2(PO4)2 glass-ceramics decays by about 58.95％within 120 h,and the intensity remains stable thereafter.The thermoluminescence(TL)curve has three peaks at 164,240,and 344℃.Minimum detectable dose(MDD)of the 0.5 mol％Gd3+-doped BaZn2(PO4)2 glass-ceramics was calculated as 0.675 mGy.The samples also exhibit good signal reusability and a broad linear dose-response range(0.3-500 Gy).Results show the excellent dosimetric properties of Gd3+-doped BaZn2(PO4)2 glass-ceramics and their potential application in radiation dosimetry.
