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(jī)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(jī)離子染料。遠(yuǎn)紅外線是紅外線中的一種,遠(yuǎn)紅外線有較強(qiáng)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(jī)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(jìn)行展望。關(guān)鍵字:鉍離子;紅外發(fā)光;機(jī)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(jì)(論文)Revie
