| Abstract: | Cadmium zinc telluride(CZT)is a preferred material for X-ray and gamma-ray detector.Thanks to the relatively high atomic number,high density and wide band-gap.CZT detector possesses sharp energy resolution and high detection efficiency without cryogenic cooling.We have developed a CdZnTe detector with an energy resolution of 3.45%(FWHM)at 59.54 keV at room temperature.and it is used for X-ray fluorescence analysis.In this paper,leakage current,energy resolution and long term stability of the CZT detector are discussed. |
