Downconversion in Pr3+–Yb3+ co-doped ZBLA fluoride glasses
Fluorozirconate ZBLA glasses with molar composition 57ZrF4–34BaF2–5LaF3–4AlF3–0.5PrF3–xYbF3 (from x=0 to 10) were synthesized to evaluate the rate of the conversion of visible photons into infrared photons. The emission spectra in the near infrared (NIR) at 950–1100nm and the luminescence decays in...

| description | Fluorozirconate ZBLA glasses with molar composition 57ZrF4–34BaF2–5LaF3–4AlF3–0.5PrF3–xYbF3 (from x=0 to 10) were synthesized to evaluate the rate of the conversion of visible photons into infrared photons. The emission spectra in the near infrared (NIR) at 950–1100nm and the luminescence decays in the visible and NIR indicate an energy transfer from Pr3+ to Yb3+ upon blue excitation of Pr3+ at 440nm. The energy transfer efficiency increases with Yb3+ concentration to reach 86% with 0.5Pr3+–10Yb3+ co-doping (in mol%). However, the quenching of the Yb3+ emission strongly reduces the efficiency of the downconversion process: the decay time values decrease from 600µs (x=0.5mol%) to 85µs (x=10mol%).
•We synthesized 0.5Pr3+–xYb3+ co-doped ZBLA glasses (from x=0 to 10mol %).•Photoluminescence of Yb3+ was observed at 980nm under blue excitation.•Time resolved measurements have been performed in the visible and near infrared.•Energy transfer efficiency from Pr3+ to Yb3+ reaches 86% in 0.5 Pr3+–10Yb3+ glass. |
