Abstract
Carbon ions at an energy of 35 keV with a dose of 5×10 16 cm −2 were implanted into SiN x O y films grown on crystalline silicon by plasma enhanced chemical vapor deposition. Intense photoluminescence (PL) peaked at about 550 nm is observed in the implanted films under an excitation of 441.6 nm laser line. The PL intensity varies with annealing temperature, and reaches a maximum at the annealing temperature of 600 °C. The luminescence may originate from the complex of Si, N, O, and C in the films.Keywords
