Abstract
The effect of
rapid thermal processing (RTP) on surface plasmon (SP) oscillation characteristics of Ag island film are
reported in this paper. With increase of the annealing temperature, the SP resonance band showed a blue shift at first and
red shift finally which can be attribute d to the morphology change of the Ag island films The SP bands of large island si ze
films blue shift more in comparison with that of small islands due to their more obvious change of morphology upon
annealing. By comparing the SP evolution of the Ag islands under RTP at different temperatures with those upon long time
furnace annealing ( FA), it is found that the SP resonance band shifts directly to short wavelength by RTP, but the SP
resonance band blue shifts gradually with increasing the temperature by FA The difference can be ascribed to the different
heating and cooling rates betwe en the two annealing processes..
