摘要

Eu~(2+), Dy~(3+), and Er~(3+) ions codoped SrAl_2O_4 phosphors with near infrared (NIR) (at 1530 nm) long-persistent phosphorescence were synthesized by a combustion method. The NIR phosphorescence emission was realized through a persistent energy transfer process from Eu~(2+) ions to Er~(3+) ions. Optimal Er~(3+) concentration for the maximum energy transfer efficiency was determined and NIR phosphorescence persisting for more than 10 min was achieved. A model of charge trapping and energy transfer process among Eu, Dy, and Er ions in SrAl_2O_4 host was proposed.
