Spectroscopic Properties and Energy Transfer of Er3+-doped and Er3+/Yb3+ Co-doped Tellurite Glasses
is a key element of the 1.5 m window telecommunication system. In recent years
in order to raise amplifier gain parameters
many solutions
such as Er

were introduced. In this paper

glass were prepared by high-temperature melt-quenching method. The absorption spectra and emission spectra of Er

- doped glass
the emission spectra and lifetimes of Er
3+
/Yb
3+
co-doped glass were measured and investigated. The intensity parameters
t
(t

the infrared emission intensity ratio of Yb
3+
ions to Er
3+
ions and mechanism of counter energy transfer were discussed in Er
3+
/Yb
3+
co-doped glass. The results indicate that a maximum value of full width half maximum (FWHM) of 1.53 m infrared emission spectra is 90 nm in Er
3+
-doped glasses
and the suitable content of Yb
3+
ions is helpful for decreasing the disappearing population velocity of Er
