摘要

•Dy3+/Eu3+ co-doped ZPBT luminescent glasses prepared by melt-quenching technique.•White light and orangish-red emission were achieved via energy transfer.•The interaction among Dy3+ and Eu3+ was dipole-dipole in nature.•ZPBT glasses revealed high thermal stability and inconspicuous chromaticity shift.•A practical device was fabricated using as-synthesized glass with n-UV LED chips.
