N2 - The present paper, we describe the development of an α ray imaging detector based on a ZnO single crystalline scintillator and a positionsensitive photomultiplier tube (PSPMT). The ZnO crystal was grown by the hydrothermal synthesis method with 2-in.-ø in diameter. The ZnO specimen was polished out to be 0.5mm in thickness. After optically coupling with PSPMT, the crystal was irradiated with 241Am-ray for evaluation of both spatial resolution and pulse height spectrum. Using the charge center of the gravity method, two-dimensional α ray images were successfully obtained. The efficiency of the energy window in terms of imaging quality was also examined
