摘要 本文分為兩部份,一是分別使用紅外線快速熱退火與脈衝雷射熱退火系統對一維型態氧化鋅奈米柱樣品作處理,而本文我們將重點放在利用光激螢光光譜研究其紫外放光經上述處理後的變化。從螢光光譜我們得知樣品經熱退火處理後,螢光強度皆有先增強再減弱後增強的趨勢。這些現象可以由鋅的熔化與氧化鋅經退火後結晶性改變來解釋。 第二部份為使用紅外線快速熱退火系統對聚苯胺樣品作熱處理,並利用光激螢光光譜對樣品作光學上的研究,也對樣品作導電度的量測。由實驗我們可得知聚苯胺經快速熱退火處理,其螢光強度與導電度皆會隨退火溫度上升有先增加後減少的趨勢,且大約在150℃時有最大值。隨著熱退火溫度增加,我們認為其非結晶結構變較為規則,因此使得其螢光強度與導電度增加。
Abstract This thesis is divided into two parts, in the first one, we investigate the photoluminescence (PL) of one-dimension zinc oxide (ZnO) nanorods which were treated by rapid thermal annealing (RTA) and pulsed laser annealing (PLA), respectively. We focus on the UV emission of the ZnO nanorods. In the RTA and PLA treatments, we found that the PL intensity increases first and then decreases. This trend is attributed to the melting of zinc and the crystallization of ZnO. In the second part, we studied the effects of PL and conductivity of polyaniline (PANI) after RTA. We found that the PL intensity and the conductivity increase gradually and then decrease with increasing the RTA temperature. There is a maximum magnitude of PL and conductivity around 150℃. The enhancement of PL and conductivity can be explained by the generation of regularized amorphous structure with annealing.
