Abstract
Thisworkaims at the development of a reactive ultrafiltration membrane scintillator for rapid activity determination and isotopic quantification of waterborne special nuclear materials (SNMs) based on ZnS:Ag. The effects of the pH of the precursor solution on ZnS:Ag synthesized under various conditions of temperature and time by the hydrothermal reaction synthesis method (200℃ for 6 hours, pH from 1 to 12; 100℃ for 2 hours, pH from 7 to 12;60℃ for 6 hours, pH from 7 to 12) were investigated. Samples were characterized on their structure, morphology and luminescence by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), photoluminescence (PL) and radioluminescence under X-ray excitation (RL) measurements, respectively. Cubic ZnS phase was determined by both XRD and Raman. PL and RL measurements revealed the contribution of distinct luminescence centers, and it was found out that the relative intensity of the blue, green and red emissions could be tuned by the hydrothermal reaction conditions.
