银 nanorod 数组被交流电(交流) 制作了并且搏动在多孔的阳极的铝氧化物(AAO ) 的直接水流(DC ) 电极淀积有 19, 38,和 65 nm 的控制毛孔直径的模板分别地。他们有事件角度和 nanorods 长度的光吸收性质的变化(相应于电极淀积时间) 被调查了。光吸收系列证明纵的表面电浆子回声(LSPR ) 的位置达到顶点随刺激光的事件角度的增加有小 blueshift。当 nanorods 的方面比率增加时,到某个波长的 LSPR 山峰第一 redshifts 然后 blueshifts 的位置。而且, LSPR 山峰的位置能被调节,从 550 nm 到 900 nm,它使联合刺激来源的各种各样的波长帮助放射的精力转移到领受人可能。
Silver nanorod arrays have been fabricated by alternat-ing current(AC) and pulsed direct current(DC) electrodeposition in porous anodic aluminum oxide(AAO) templates with controlled pore diameters of 19,38,and 65 nm,respectively.The variation of their optical absorption properties with the incident angle and the nanorods length(corresponding to the electrodeposition time) has been investigated.Optical absorption spectra show that the posi-tion of longitudinal surface plasmon resonance(LSPR) peak has a small blueshift with the increase of incident angle of the excitation light.While the aspect ratio of the nanorods increases,the position of LSPR peak first redshifts and then blueshifts to a certain wave-length.Furthermore,the position of LSPR peak can be tuned,ranging from 550 nm to 900 nm,which makes it possible to cou-ple various wavelength of excitation source to assist radiative en-ergy transfer to the acceptor.
