Temperature is the most fundamental parameter,the optical temperature sensor has gained tremendous importance.[1,2] In contrast to other temperature sensor,the optical sensors by UC luminescence,which based on the florescence intensity ratio(FIR)technique,process the unique advantages such as high sensitivity,high accuracy,contactless and large-scale imaging.[3,4] In this work,the intensive up-conversion(UC)photoluminescence and temperature sensing behavior of Er3+ doped Bi7Ti4NbO21(BTN)ferroelectric ceramics prepared by a conventional solid-state reaction technique have been investigated.The X-ray diffraction and field emission scanning electron microscope analyses demonstrated that the Er3+ doped BTN ceramics are single phase and uniform flake-like structure.
