Er3+–doped 0.94KNN–0.06Ca(Bi0.5Nb0.5)O3: a fluorescent transparent ceramic with optoelectronic multi-functionality

In this work, 0.94(K 0.5 Na 0.5 )NbO 3 –0.06Ca(Bi 0.5 Nb 0.5 )O 3 – x wt%Er 3+ ( x  = 0, 0.1, 0.2, 0.3, 0.4) fluorescent transparent ceramics were prepared using traditional solid-phase method. The ceramics are of pseudo-cubic phase, and the average grain size of ceramic reaches the nanometer level....
