| 英文摘要 | In the present paper, we investigate the near-infrared (nir) luminescence of tb3+-yb3+ codoped lanthanum borogermanate (lbg) glasses under visible and ultraviolet light excitation. the results indicate that nir quantum cutting occurs through cooperative energy transfer from tb3+ to yb3+ ions when only 4f (8) levels of tb3+ ions are excited in the wavelength region of 300-490 nm. the highest quantum efficiency under the excitation (5) d (4) level of tb3+ at 484 nm is 146%. ultraviolet excitation that populates the charge transfer band (ctb) of yb3+ near 270 nm does not result in quantum cutting as the fast nonradiative decay from ctb to (2) f (5/2) level dominates. these materials are expected to be used as a converting layer for silicon solar cells to enhance their efficiency by splitting each high-energy photon into two nir photons. |
