Abstract

CdGa2S4 single crystals have been grown from a presynthesized source material by closed-tube iodine vapor transport, and their X-ray dosimetric properties have been studied. Their X-ray sensitivity coefficient K ranges from K = 1.26 × 10−11 to 1.39 × 10−10 A min/(V R) at effective X-ray hardnesses V a = 25–50 keV and dose rates E = 0.75–78.05 R/min, and increases with X-ray dose. The K(V a) curve has a negative slope, in contrast to the K(E) curve. The photocurrent-dose curves of the CdGa2S4 single crystals demonstrate that the steady-state X-ray photocurrent is a power-law function of X-ray dose rate: ΔI E,0E α . With increasing V a, the slope of the curves sharply decreases and α approaches unity.
