Patent ID: 7625595

Claim:
A method of monitoring synthesis of PCMO precursor solutions, comprising: preparing a PCMO precursor solution; withdrawing samples of the PCMO precursor solution at intervals during a reaction phase of the PCMO precursor solution synthesis; analyzing the samples of the PCMO precursor solution by UV spectroscopy to determine UV transmissivity of the samples of the PCMO precursor solution; forming a PCMO thin film from the samples of the PCMO precursor solution; determining electrical characteristics of the PCMO thin films formed from the samples of the PCMO precursor solution to identify PCMO thin films having optimal electrical characteristics; determining the UV transmissivity range of the PCMO thin films having optimal electrical characteristics; and monitoring future PCMO precursor solution synthesis from the UV transmissivity range of the PCMO thin films having optimal electrical characteristics to synthesize PCMO precursor solutions which will result in PCMO thin films having optimal electrical characteristics.
