N2 - CdSe single crystals are considered as promising candidates for radiation detectors, however, the progress is limited by the fabrication of high-quality CdSe single crystals. Herein, we reported a CdSe-based radiation detector, exhibiting superior detection performance for α-particles and γ-rays. The FWHM of the X-ray rocking curve of CdSe (100) plane was determined to 0.03°. The as-grown CdSe single crystal exhibited a high room-temperature resistivity of 1.83×109Ω cm. Moreover, the detector exhibited an energy resolution of ∼13.22% and ∼11.21% for α-particles and γ-rays, respectively. The hole mobility-lifetime product (μτ(h)) in experimental of the detector up to 2.20 × 10−4 cm2 V−1 was reported by using the Hecht equation.
