摘要:
Two ternary precursor lanthanides (abbreviated as Ln, terbium and europium) complexes with 3-methacryloxypropyltrimethoxysilane and 1, 10-phenalithroline were successfully prepared. Then the resulting compounds and tetraethoxysilane further form luminescent hybrid systems with the hydrolysis and condensation of their alkoxy groups through an in situ sol-gel process. The intramolecular energy transfer process runs smoothly within these molecular-based hybrids in terms of sensitized functions of 1,10-phenanthroline and strong characteristic green or red emission of Tb3+ and Eu3+ has been achieved.
