Barium gallo-germanate glasses co-activated with Cr3+/Er3+ and Cr3+/Er3+/Ln3+ (Ln = Yb, Ho) for near-infrared luminescence applications

Abstract Near-infrared luminescence properties of barium gallo-germanate glasses co-activated with Cr 3+ /Er 3+ and Cr 3+ /Er 3+ /Ln 3+ (Ln = Yb, Ho) have been studied for the first time. Compared to Cr 3+ /Er 3+ co-doped sample, near-infrared emission of Er 3+ at 1534 nm in Cr 3...
