    Excitation Induced Tunable Emission in Ce3+/Eu3+ Codoped BiPO4 Nanophosphors by Sarabjot Singh, G. Lakshminarayana, Manoj Sharma, Thang Duy Dao, K. Chen, Yoshiki Wada, T. Takeda, T. Nagao

    Published 2015-01-01
    “…These results demonstrate that by appropriately tuning the excitation wavelength of these codoped nanophosphors the emission color in the visible region (blue and orange) can be flexibly controlled in a single sample without varying its chemical composition and size. The mechanism for this excitation energy dependent tunable emission is explained on the basis of nonenergy transfer (ET) occurring among Ce3+/Eu3+ dopant ions.…”
