2、吸收能量轉(zhuǎn)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(yīng)和共振效應(yīng),它易被物體吸收并轉(zhuǎn)化為物體的內(nèi)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(guān)鍵字:鉍離子;紅外發(fā)光;機理;影響因素III濱州學(xué)院應(yīng)用化工技術(shù)專業(yè)畢業(yè)設(shè)計(論文)ReviewonBi-dopedinfra-luminescencematerialsAbstractBismuthionsinfraredglowlighthasgoodofappli
