Downconversion in Pr3+–Yb3+ co-doped ZBLA fluoride glasses

Studies on Pr3+–Yb3+ codoped ZBLA as rare earth down convertor glasses for solar cells encapsulation

“…In the previous studies [34] the ET from Pr 3+ to Yb 3+ was demonstrated in the Pr 3+ -Yb 3+ co-doped ZBLA glasses. The photoluminescence emission in the NIR range, of the Pr 3+ ( 3 P 0 ?…”

“…The profile of the Yb 3+ emission band changes as the main emission peak at 978 nm tends to decrease with Yb 3+ concentration. This is explained by the Yb 3+ reabsorption process [34].…”

Study with Analytical Equations of Absorption Spectra Containing Interference Dips in Fluoride Glasses Doped with Cr3+

“…All the operations for glass synthesis were done inside a dry gloves box because of the sensitivity of the fluorides to hydrolysis. The methods have been described in detail earlier. ,, Finally, the samples were cut and polished for optical measurements.…”

“…The methods have been described in detail earlier. 6,17,18 Finally, the samples were cut and polished for optical measurements. Absorption spectra were recorded using a PerkinElmer Lambda 1050 spectrophotometer at room temperature from 12000 to 28000 cm −1 .…”

Spectral outputs of Yb3+/Pr3+ doped Tellurite glasses for solid-state lighting

“…This decrement is proposed to be due to concentration quenching (19,20). The emission of Pr 3+ ions around 910 nm corresponding to 3 P0 → 1 G4 transition decreases down to zero at 6 mol% Yb 3+ ion concentration, and 2 F5/2 → 2 F7/2 emission intensity at 978 nm of Yb 3+ ions decrease by increasing Yb 3+ ion concentration due to the reabsorption process of Yb 3+ (21). The range of 1050 nm emission of Pr 3+ ions which is attributed to 1 D2 → 3 F3,4 energy transition as an occurrence by the cross-relaxation process of 3 P0 + 3 H4 → 3 H6 + 1 D2 in Yb 3+ /Pr 3+ co-doped SiO2-Nb2O5 nanocomposites had been reported (22).…”
