2、吸收的能量转化为光辐射的过程，而红外发光是某一段波长的光波吸收能量转换为光辐射的过程。近红外有机发光材料主要集中在两大类：一是稀土元素配合物；二是有机离子染料。远红外线是红外线中的一种，远红外线有较强的渗透力和辐射力，具有显著的温控效应和共振效应，它易被物体吸收并转化为物体的内能。本文章就铋离子掺杂红外发光材料的机理以及影响因素做出理论解释，并就铋离子掺杂红外发光材料的前景进行展望。关键字：铋离子；红外发光；机理；影响因素滨州学院应用化工技术专业毕业设计（论文）IIReview on Bi-doped infra-luminescence materials AbstractBismuth i
