    摘要: A method of monitoring synthesis of PCMO precursor solutions includes preparing a PCMO precursor solution and withdrawing samples of the precursor solution at intervals during a reaction phase of the PCMO precursor solution synthesis. The samples of the PCMO precursor solution are analyzed by UV spectroscopy to determine UV transmissivity of the samples of the PCMO precursor solution and the samples used to form PCMO thin films. Electrical characteristics of the PCMO thin films formed from the samples are determined to identify PCMO thin films having optimal electrical characteristics. The UV spectral characteristics of the PCMO precursor solutions are correlated with the PCMO thin films having optimal electrical characteristics. The UV spectral characteristics are used to monitor synthesis of future batches of the PCMO precursor solutions, which will result in PCMO thin films having optimal electrical characteristics.

    摘要: A method of fabricating an electroluminescent device includes preparing a wafer and a doped-silicon oxide precursor solution. The doped-silicon oxide precursor solution is spin coated onto the wafer to form a doped-silicon oxide thin film on the wafer, which is baked at progressively increasing temperatures. The wafer is then rapidly thermally annealed, further annealed in a wet oxygen ambient atmosphere. A transparent top electrode is deposited on the doped-silicon oxide thin film, which is patterned, etched, and annealed. The doped-silicon oxide thin film and the wafer undergo a final annealing step to enhance electroluminescent properties.
