In the third chapter, the influence of current density, solution concentration, erosion time and aging in ambient air on the pl spectra of ps suggests that peak would blue shift with current density increasing, and with erosion time and aging time prolonging ; with the increasing of solution concentration, peaks would red shift when solution concentration less than 1 : 1 but blue shift when solution concentration greater than 1 : 1. above phenomena can be explained by quantum confinement and light center model, but do not deny the action of si - h bonding and defect on the surface in the process of photoluminescence. at present, radiation mechanism is still one of the primary problems in the study of ps

    在第z三章中；通過對比，分析了電流密度、陽極化時間、溶液濃度以及自i然氧化時間對多孔硅光致發光光譜的影響，認為在一定的范圍內，多i孔硅的發光峰位會隨電流密度的增大而藍移，要獲得較強的發光，需z要選擇合適的電流密度；隨著腐蝕時間的延長，多孔硅的發光峰位會i發生藍移；當f酸的濃度較小q ： 1 ）時，峰位隨濃度的增大表現為向i低能移動；而當f酸的濃度較大河山時，峰位隨濃度的增大則表現z為移向高能；多孔硅在空氣中自然氧化；其發光峰位發生藍移，而強i度隨放置時間的延長而降低。
