Photoluminescence of Eu(DBM)_3Phen-embedded Silica Nanospheres Synthesized in Microemulsion
Eu(DBM)<SUB>3</SUB>Phen-embedded silica nanospheres were synthesized through a simple water-in-oil (W/O) microemulsion method. TEM observation indicates that the nanospheres are ≈40 nm in diameter and with a uniform core/shell structure. Compared to Eu(DBM)<SUB>3</SUB>Phen complex, the nano-hybrid-spheres shows similar emissions of Eu<SUP>3+</SUP> ions under 355-nm excitation. By dynamic analysis at low temperature and laser selective excitation spectra, we found that there are two luminescent centers formed in the nanohybrids.
