抜粋

Optical characteristics of thin SiO2 films deposited from tetraethoxysilane by the plasma-enhanced chemical-vapor-deposition method were studied using synchrotron radiation. When the deposition temperature is 600°C, 7.6 eV absorption and 4.4 eV luminescence with a small decay constant (<3 ns) due to the oxygen vacancy (≡Si-Si≡) are observed. The decay curve of the 4.4 eV luminescence has the appearance of a stretched-exponential function. This indicates that the decay constant consists of widely distributed components, reflecting structural distortion of the film.
