A chemical solvent preparation method of molybdate luminescent film belongs to the preparation methods of molybdate luminescent film. The steps are that: a) the pre-treatment of substrates---metal molybdenum film with the purity of 99.9 percent is degreased by acetone and kibbled with metallographic sand paper. Then the mixed acid is added to erode the film for 1-3 minutes. Next the ultrasonic cleaning is made in deionized water. The substrates with adsorptive activity as well as smooth surface are obtained. b) The deposition of the film--- 100.0ml A(OH)2 and 1-10ml H2O2 solution or 1-10ml NaClO solution are added into a sealed reaction tank, wherein, A is Ca, Sr or Ba. The pre-treated substrates are suspended in the solution with nitrogen inflating into for 20 minutes. And then the reaction tank is sealed. The reaction lasts for 30-200 hours under 20-40 DEG C. Then the substrates with films are put out and immersed and dried in warm water. In the end the ...
