| Abstract | Scintillator materials are phosphors that convert one ionizing radiation to thousands of visible photons immediately by quantum cutting and they have played a major role in radiation detector applications including medical, security, well-logging, and basic physics [1]. One of the famous scintillators is Ag-doped ZnS that is generally used for charged particle detectors and exhibits the largest light yield in known scintillators [2]. Although Ag-doped ZnS was intensely studied previously, optical and scintillation properties of undoped ZnS were not investigated. Therefore in this study, we focused to investigate basic optical and scintillation properties of the non-doped ZnS. The size of the sample was 10 × 10 × 2 mm and wide surfaces were polished. At first, optical properties, including transmittance, photoluminescence, and photoluminescence decay time profiles were studied systematically. Then, ionizing radiation responses such as X-ray radioluminescence, -ray radioluminescence, -ray excited pulse height spectrum, scintillation decay time, and thermally stimulated luminescence (TSL) properties were investigated. Figure 1 exemplifies X-ray induced radioluminescence spectrum of undoped ZnS. Two intense peaks appeared at 430 and 520 nm with quite high emission intensity. In the conference, optical and radiation responses of undoped ZnS will be discussed. |
