Properties of Visible and NIR Emissions with Quantum Cutting in Ce3+-Yb3+-codoped Y3Al5O12 Powder Materials
-doped YAG powders were prepared and the energy transfer (ET) mechanism with (Ce
3+
)
*
-Yb
3+
charge transfer transition in the powders was evaluated by the photoluminescence (PL)
the photoluminescence excitation (PLE) and the lifetime. The possibility of the NIR emission of QC was also discussed because the 1 000 nm emission of Yb
3+
just meets the largest spectral response of c-Si solar cells
which may have potential application in enhancing the conversion efficiency of c-Si solar cells.
