摘要
Silicon carbonitride (SiCN) films were deposited by radio-frequency magnetron sputtering and then annealed at different temperatures from 1100 to 1300 degrees C in hydrogen atmosphere. The as-deposited films and films annealed at 1100 degrees C did not show photoluminescence (PL), whereas strong PL peaks appeared at 355 and 469 nm after annealing at 1200 and 1300 degrees C. X-ray diffraction, transmission electron microscope, and Fourier transform infrared spectrometer results show that the enhancement of PL properties is due to the change of microstructure and composition.
