| Abstract: | Ternary compounds MeI AgI (Me:K,Rb,Cs) thin films were grown by vacuum evaporation.A dedicated vacuum system with a cryostat was developed,which is capable of making optical spectroscopic analysis in vacuum,at liquid nitrogen temperature.The exciton spectroscopic analysis of the ternary compounds thin films at 80 K was also discussed. |
