2、素化合。而發(fā)光是物體將某種方式吸收的能量轉(zhuǎn)化為光輻射的過程，而紅外發(fā)光是某一段波長的光波吸收能量轉(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）Revie
