A method of forming a film of metal fluoride in which there is combined a metallo-organic compound solvent solution and an organic fluoride to form a casting liquid. The casting liquid is then coated by a method such as dip coating or spin coating to form a coating on a substrate. The coated substrate is then heated to decompose the metallo-organic compound and organic fluoride resulting in recovery of a metal fluoride coated substrate. The metal fluorides formed may be fluorides of lithium, sodium, potassium, magnesium, calcium, strontium, or barium, lanthanum, yttrium, or the oxifluoride of europium, erbium and other rare earths.
