We report on the luminescent properties of ZnO-LiYbO2 hybrid phosphor, in which the broadband spectral modification can be realized to benefit the enhancement of silicon solar cell photovoltaic conversion efficiency. Under the excitation of ZnO band-band absorption and exciton absorption in the near-UV region, the intense Yb3+ emission around 1000 nm can be observed. The occurrence of energy transfer from ZnO to Yb 3+ was proved by the excitation and emission measurement. The emission spectra between the ZnO-LiYbO2 hybrid phosphor and the LiYbO2 crystal under the direct excitation of Yb3+ ions with 937 nm LD was compared, which indicates that the Yb3+ ions that were diffused into ZnO lattice with the help of Li+, rather than those constitute of LiYbO2 crystals, are responsible for the intense infrared emission. © 2011 Ceramic Society of Japan.
