摘要	The growth, structure and spectral properties of a Cr4+:Ca2GeO4 single crystal have been reported in this paper. XPS analysis demonstrated that the chromium in the single crystal is tetravalent; this is further confirmed by fluorescence spectroscopy. The near-infrared, visible absorption and near-infrared luminescence spectrum of the Cr4+:Ca2GeO4 crystal are presented in this paper. In the absorption spectra, the transitions from the (3)A(2) ground state to the three orbital components of the T-3(1) and T-3(2) excited state are observed. The range of the fluorescence spectroscopy band of the Cr4+:Ca2GeO4 crystal at room temperature is from 1000 nm to 1600 nm. The single band with a maximum peak at 1317 nm at room temperature is attributed to the T-3(2) -> (3)A(2) transition of the Cr4+ ions. The FWHM of the fluorescence spectrum is 201.19 nm, and the fluorescence lifetime and emission cross section are up to 12 mu s and 4.61 x 10(-19) cm(2), respectively. (C) 2015 Elsevier B.V.
