Cobalt phosphate and cobalt lithium phosphate thin films were prepared by spin casting aqueous precursor solutions onto silicon substrates.  The influence of the dehydration temperature was studied by systematically increasing the soft bake temperature between deposition cycles.  In cobalt lithium phosphate films two methods were used to control the cation ratio present in the films.  One series of samples was prepared by spin casting alternating layers of cobalt phosphate and lithium phosphate solutions.  The ratio of cobalt phosphate to lithium phosphate layers was varied in order to control the cation ratio.  In the second series, the two precursor solutions were mixed in varying ratios before spin casting.  In each case, the final film compositions were examined by etching the films with nitric acid and using atomic absorption spectroscopy to measure the concentration of the cobalt and lithium metals.
