Abstract

The Pr-doped solid solutions from (Ba,Ca)(Ti,Zr)O (BCTZO) system were successfully synthesized using an efficient and low-energy consuming route-the Pechini method combined with the sintering at relatively low temperature (1450 °C). The obtained materials were characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The dielectric properties were systematically studied. The Pr-doped BCTZO diphasic material generates intense and broad red photoluminescence (PL) emission at room temperature. The optical properties were significantly improved with the Ti substitution by Zr ions. As a result, the Pr-doped (Ba,Ca)(Ti,Zr)O ceramics is a promising candidate for environmentally friendly, multifunctional material by combining good dielectric and photoluminescent properties with prognosis for the manifestation of strong photoluminescent and mechanoluminescent effects.

摘要

采用一种高效且低能耗的方法——佩琴尼法，并结合相对低温（1450℃）烧结，成功合成了（Ba,Ca）（Ti,Zr）O（BCTZO）体系的掺镨固溶体。通过X射线衍射（XRD）和扫描电子显微镜（SEM）对所得材料进行了表征。系统研究了其介电性能。掺镨的BCTZO双相材料在室温下产生强烈且宽泛的红色光致发光（PL）发射。通过用Zr离子取代Ti，光学性能得到显著改善。因此，掺镨的（Ba,Ca）（Ti,Zr）O陶瓷通过将良好的介电和光致发光性能与强发光和机械发光效应表现的预后相结合，是一种有前景的环保多功能材料候选物。
