Multifunctional Performance of Europium-Doped Feldspar Ceramics

Abstract:

We have successfully developed a multifunctional ceramics, europium-doped feldspar MAl2Si2O8:Eu (MASE, M=Ca, Sr, Ba) and demonstrated that MASE was able to emit high mechanoluminescence (ML), strong photoluminescence (PL) and electroluminescence (EL). According to the XRD measurement result, the space group of MASE was identified to P1 .The ML intensity increased proportionally with the increase of the compressive load, which suggests an efficient conversion of mechanical to optical energy. Furthermore, strong PL and EL emission from MASE were confirmed. The PL, ML, and EL spectra were found to be similar in both peak shape and position, which indicates all the emissions result from 5d-4f transition of Eu2+.
