Notes:
Observation of sequentially adjustable, intense, and stable emissions at room temperature from amorphous silicon-rich oxide thin films without any thermal annealing is reported. Hydrogenated amorphous silicon-rich oxide (SiOx:N:H, 0〈x〈2) thin films were deposited by plasma-enhanced chemical-vapor deposition with a mixture of 5% silane in argon and nitrous oxide gases. The strong naked-eye-seeing photoluminescence (blue–white–orange) could be adjusted by changing the process gases flow rate ratio Γ (=[SiH4]/[N2O]). The degree of silicon richness was determined from secondary ion mass spectrometry. The microstructure-bonding configuration was examined by Fourier transform infrared spectroscopy. The implications of these studies for understanding the origins of silicon-based luminescence are discussed. © 1999 American Institute of Physics.
