Description |
The effects of concentration of Er(3+) ions in tellurite glasses on the decay time, spectral width and weighted spectral peak are studied. A broad emission spectrum of width 121 nm peaked at wavelength of 1.5 mum is obtained in 2.5 mol% Er doped glasses. The maximum decay time of (4)I(13/2) —> (4)I(15/2) transition (at wavelength 1.5 mum) is about 4.5 ms for 1.0 mol% Er doped glasses. Strong green and red upconversion emission at emission 550 nm ((4)S(3/2) —> (4)I(15/2)) and 670 nm ((4)F(9/2) —> (4)I(15/2)) are observed from Er(3+)-doped tellurite glasses upon continuous wave excitation at 975 nm. It is found that the upconversion efficiency goes up with the increasing concentration of the Er(3+) ions. (C) 2004 Elsevier B.V. All rights reserved.
