Energy Transfer between Tb3+ and Eu3+ in LaPO4: Pulsed versus Switched‐off Continuous Wave Excitation

Autor: Yuxia Luo, Zhenyu Liu, Hon Tung Wong, Lei Zhou, Ka‐Leung Wong, Kwok Keung Shiu, Peter A. Tanner

Publikováno v: Advanced Science, Vol 6, Iss 10, Pp n/a-n/a (2019)

Abstract The energy transfer (ET) between Tb3+ and Eu3+ is investigated experimentally and with available theoretical models in the regime of high Tb3+ concentrations in ≈30 nm LaPO4 nanoparticles at room temperature. The ET efficiency approaches 1
