2、而紅外發(fā)光是某一段波長的光波吸收能量轉換為光輻射的過程。近紅外有機發(fā)光材料主要集中在兩大類:一是稀土元素配合物;二是有機離子染料。遠紅外線是紅外線中的一種,遠紅外線有較強的滲透力和輻射力,具有顯著的溫控效應和共振效應,它易被物體吸收并轉化為物體的內能。本文章就鉍離子摻雜紅外發(fā)光材料的機理以及影響因素做出理論解釋,并就鉍離子摻雜紅外發(fā)光材料的前景進行展望。關鍵字:鉍離子;紅外發(fā)光;機理;影響因素III濱州學院應用化工技術專業(yè)畢業(yè)設計(論文)ReviewonBi-dopedinfra-luminescencematerialsAbstractBismuthionsinf
