Nano-thin films precursors of MgO and In2O3 were synthesized by sol-gel method and thin films were prepared by dip coating method. The influence of eataluminescence (CTL) signals of some organic gases on MgO thin film and In:O3 thin film with the preparing condition of colloid solution pH, calcination temperature and film layers were discussed. From the experimental data analysis, we can conclude that for detecting ethylene glycol methyl ether vapor, MgO thin film has the optimum CTL signal, under the condition as follows: the colloid solution of pH = 8, calcinations temperature of 550 ℃, coating film of 5 layers. For detection of acetic acid vapor, In2O3thin film has the optimum CTL signal, under the condition as follows: the colloid solution of pH = 5, calcinations temperature of 550 ℃, coating film of 5 layers.
