Preparation and Luminescence Properties of Eu(BA)3phen@MSBA-15 in Material Engineering
Abstract:
Eu(BA)3phen@MSBA-15 composite was prepared and systematacially characterized. The Eu(BA)3phen complexes are uniformly distributed into the channels of the modified SBA-15. The luminescent properties of Eu(BA)3phen@MSBA-15 composite are systematically studied in contrast to the pure complexes. The results indicate that the excitation bands assigned to the π-π* electron transition of the ligands in Eu(BA)3phen@MSBA-15 are narrower than that in Eu3+ complexes, and the 5D0-7F0 transitions emmission become partly allowed. The emission lines for the 5D0-7F2 transitions become broader. The photostability of the emissions improves considerably, which is essential for future applications of RE complexes in molecular optical and electrical devices.
