【Abstract】 Abstract Porous Silicon material has been fabricated by stain-etching single crystalline silicon in HF and HNO3 solutions. We have studied the visible photoluminescence characteristics of porous silicon formed by above method, specially the dependence of PL emission intensities and wavelength peaks on excitation intensities and wavelength peaks, as well as the stability and transient response characteristics.更多还原
