Enhanced broadband near-infrared luminescence and peak wavelength shift of Yb–Bi ions co-doped phosphate glasses containing Lu3+

摘要: Abstract Yb–Bi ions co-doped phosphate glasses with different Lu 2 O 3 concentrations were prepared. The effects of 3+ addition on broadband emission intensity, peak wavelength shift and measured fluorescence lifetime investigated. maximum intensity is about 7.3 times higher than that no doped glasses. shows obvious blue-shift. lifetimes near the wavelengths tend to increase. results indicate can be introduced into glass matrix enhance change wavelength, reinforce energy transfer process for its dispersant effect.
