Scintillator detector is a kind of the radiation detector in common use,and scintillator is the core part in scintillator detector. Organic crystal scintillator is the most preponderant radiation detecting material for its high irradiance efficiency. But because of the high vapor pressure,thermal instability and poor thermal conductivity of organic materials at melting temperature,the preparation conditions of organic crystal scintillator are very rigorous. The main preparation methods of organic crystal ar...
