Role of Synthesis Method on Luminescence Properties of Europium(II, III) Ions in β-Ca2SiO4: Probing Local Site and Structure

Role of Synthesis Method on Luminescence Properties
of Europium(II, III) Ions in β-Ca2SiO4: Probing Local Site and Structure
Ziqing Li, Santosh Kumar Gupta, Huaidong Jiang, Xiulan Duan, Rajaboopathi Mani
Europium was used as a local spectroscopic probe to investigate the changes in its symmetry in β-Ca2SiO4 synthesized by Pechini (C2SP) and hydrothermal (C2SH) methods. The emission intensity was increased for Eu2+ whereas it diminished for Eu3+ doped C2SH compared to C2SP. The charge-transfer band in the excitation spectra of Eu3+ doped C2SH was blue-shifted about 10 nm compared to that of C2SP.
