摘要：

Spectroscopic properties of various concentrations Dy3+-doped silicate glasses were characterized by excitation and emission spectra. The optimal doping concentration of Dy3+ ions was found to be 3.0 wt%, and the nature of resonance energy transfer was confirmed to be electric dipole-dipole interaction according to Huang's rule. Simulation of white-light for these glasses was also performed by varying the excitation wavelength. The results show that the white-light luminescence color could be tuned to various wavelength excitations, and the present silicate glass is more suitable for generation of white-light for blue LED chips.
