Abstract Manipulating the energy transfer process between the dopants can realize efficient modulation of photoluminescence, which is essential for fabricating optoelectronic devices. This work presents the polarization-assisted energy transfer process between Er3+ and Dy3+ ions in borate glass-ceramics system for the first time. The overall photoluminescence intensities increased gradually as undergoing polarization engineer. The promoted energy transfer process from Er3+ to Dy3+ is obtained by emission spectra and verified by decay dynamics, which can be attributed to the slight tuning of ionic environment around doping ions. Herein, the tunable energy transfer process inspired by polarization may provide guidance for fabricating high-performance optoelectronic devices.
