Rare earth ion-doped fluorescent glass has become a hotspot due to its characteristics.This work shows that the prepared Dy3+ and Dy3+/Eu3+ doped glasses have white light emission under ultraviolet excitation.There is a higher yellow light/blue light (Y/B) value,indicating an increase in the covalentity of Dy-O,and decrease in the symmetry with the increasing concentration of dopants (Dy3+).The correlated color temperature (CCT) can be effectively reduced by the red light emission of Eu3+,and the order of influence of excitation wavelength on CCT is 395 nm＞ 382 nm ＞ 365 nm.The delay curve demonstrates the energy transfer from Dy3+ to Eu3+.The glass has the characteristics of anti-blue light damage and wide tunable color temperature,which illustrates that it has potential application in the field of white LED.
