纳米长余辉发光材料CaTiO3∶Pr的制备及表征
凝胶网格沉淀法 CaTiO3∶Pr 长余辉纳米发光体
2009/4/30
以无机盐为原料，以明胶为分散介质，采用凝胶网格沉淀法制备了掺镨的钛酸钙纳米颗粒。通过热重和差热分析，讨论了CaTiO3∶Pr共沉淀及锻烧过程中的反应机理。用透射电子显微镜观测到纳米颗粒呈类球形，粒径为100 nm左右，分散性良好。利用荧光光谱分析仪对纳米CaTiO3∶Pr粉体的发光性能进行了表征。光谱数据表明： 1 100 ℃时，煅烧1 h发光强度最大，其发光特性与传统的高温固相法相似，但烧结温度...
Enhancement of red fluorescence and afterglow in CaTiO3: Pr3+ by addition of Lu2O3
Pr3+ Red phosphor Red afterglow
2011/12/6
CaTiO3: Pr3+ with addition Lu2O3 are synthesized by conventional solid-state reaction methods. It is found that the addition of Lu leads to the enhancement of red fluorescence and phosphorescence at 6...
Enhancement of the 1D2–3H4 red emission of CaTiO3:Pr3+ with addition of rare earth oxides Ln2O3 (Ln = Lu, La, Gd) is reported.Ca2+ and Ti4+ in CaTiO3 can be substituted by Ln3+ ions as donors and acce...
