Popis: Room temperature photoluminescence (PL) has been observed from Er doped silicon rich silicon oxide films grown by magnetron sputtering. For all kinds of silicon rich silicon oxide films grown with different excess Si contents, each PL spectrum has two peaks at 1.54 and 1.38μm, which originate from Er3+ and a certain kind of defects, respectively, in the silicon rich silicon oxide. It was found that 1.54 and 1.38μm PL peak intensities are correlated with each other. The PL intensity-dependence on the excess-Si content and annealing temperature was studied in detail.
