  "abstract": "Near-infrared luminescence properties of barium gallo-germanate glasses co-activated with Cr3+/Er3+ and Cr3+/Er3+/Ln3+ (Ln = Yb, Ho) have been studied for the first time. Compared to Cr3+/Er3+ co-doped sample, near-infrared emission of Er3+ at 1534 nm in Cr3+/Yb3+/Er3+ glass is enhanced under direct excitation of Cr3+ at 600 nm. For Cr3+/Er3+/Ho3+ glass, luminescence quenching of Er3+ and enhancement of Ho3+ at 2000 nm is quite well observed. Based on spectra and decays, the energy transfer processes Cr3+ → Yb3+ → Er3+ and Cr3+ → Er3+ → Ho3+ with their efficiencies equal to nearly 55% were identified. The presence of energy transfer processes was also confirmed using the excitation spectra measured under selective monitoring emission wavelengths. The results obtained for barium gallo-germanate glasses co-activated with Cr3+/Yb3+/Er3+ and Cr3+/Er3+/Ho3+ are promising for near-infrared luminescence applications.",
