Er~(3+) doped Pb(Mg_(1/3)Nb_(2/3))O_3-0.25PbTiO_3 transparent ceramic: a multi-functional material for photonics switching and temperature measurement

摘要

We have successfully prepared the Er~(3+) doped Pb(Mg_(1/3)Nb_(2/3))O_3-0.25PbTiO_3 (PMN-PT) transparent ceramic by a two-ways sintering method. Through studying the green fluorescence originating from ~2H_(11/2) and ~4S_(3/2) under different electric field, we found that the prepared sample could be enhanced by electric field by 150%, this phenomenon is reversible so it could be used for photonics switching devices in further application. Moreover, the fluorescence intensity ratio of ~2H_(11/2) and ~4S_(3/2) was studied under different temperature. Unlike the usually exponential response, the FIR here shows a linear response to changing temperature. So an easier temperature measurement method was developed by using Er~(3+) doped PMN-PT transparent ceramic as detector.
