Abstract
The influence of Cr 3+ concentration on near-infrared emission of Ho 3+ in barium gallo-germanate glass has been studied. Near-infrared emission bands, due to 4 T 2 → 4 A 2 (Cr 3+ ) as well as 5 I 6 → 5 I 8 and 5 I 7 → 5 I 8 (Ho 3+ ) transitions, were observed under excitation of Cr 3+ . The enhanced and broadband near-infrared emission was obtained for glasses in the presence of transition metal (Cr 3+ ) and rare earth (Ho 3+ ) ions. This prosperity was optimized as a function of donor (Cr 3+ ) and acceptor (Ho 3+ ) concentration. The integrated intensities of emission bands were determined and their values are found to be maximal at 0.25 mol% Cr 3+ and 0.5 mol% Ho 3+ . The energy transfer from Cr 3+ to Ho 3+ occurs through a nonradiative process with an efficiency up to 23%. © 2019 Elsevier B.V.
