Abstract:   (52 Views)
In this research, the vertical Bridgman method has used to perform the single crystal growth of cesium iodide alkali halide. To this purpose, a vertical cylindrical furnace equipped with electric elements with five different thermal regions has been designed and constructed. The temperature gradient of the furnace can be controlled up to 1000C with 0.1C accuracy. Several cesium iodide sample crystals has been grown with this furnace and then the X-ray diffraction characterizations have been undertaken. The photoluminescence spectrum and the hardness properties of the crystals samples have been studied as well as the measurements of etch-pits of single crystals. Since the pure cesium iodide exhibits scintillation properties, the gamma-ray spectroscopy has also been undertaken.
