The absorption characteristics was that the surface plasma absorption peak appeared around 570 nm shifted to a short wavelength and strengthened as the cu composition increased. but the maximal shift range of the absorption - edge preponderated over 500 nm, and leaded that the dipolar plasma resonance absorption peak were covered up and gradually disappeared in the absorption spectrum. we theoretically explained the mechanism of the modulating action
實驗觀察到cu表面等離子體共振吸收峰位在570lun附近的吸收邊頻移量超過了500nln .理論分析表明，吸收峰位的移動主要源於偶極共振，而峰形的寬化主要由納米粒子的表面效應和量子尺寸效應引起Our group has prepared nanometer - scale metal films in layer structures on glassy carbon ( gc ) substrate by cyclic voltammetric deposition. by using co as probe molecule, we have revealed for the first time, abnormal ir effects ( aires ) on these layer nanostructured films. the alres consists of several abnormal ir features including the enhancement of ir absorption, the inversion of ir band direction ( anti - absorption ), and the increase of fwhm ( increase of the number of different adsorption sites )
本研究小組採用電化學循環伏安電沉積法在gc基底上制備層狀納米結構金屬薄膜，以co作為分子探針，觀察到異常紅外效應（ aires ）光譜特徵，即co等探針分子發生紅外吸收增強、紅外譜峰方向倒反（反吸收）和譜峰變寬（振動能級離散程度增加） 。From absorption spectra and the second - order derivative spectra, three absorption speaks of excitons were clearly resolved. at the same time, the first exciton absorption peak got stronger with decreasing nanocrystals size. blue shifts due to quantum confinement were observed obviously
納晶吸收譜及二次微分譜的測量結果表明，納晶在室溫出現了三個激子吸收峰，第一激子吸收峰隨納晶半徑減小而增強，同時清楚地觀察到納晶受限導致的光譜藍移。
