co-doped borosilicate glasses have been prepared by high-temperature solid-phase melting. Under 978 nm semiconductor laser excitation
the up-conversion emission spectra of the samples were measured
and up-conversion mechanism was analyzed. The emission intensities of Eu
3+
ions at 595 nm and 692 nm were enhanced with increasing concentration of Er
3+
Yb
3+
respectively. And emission intensity at 692 nm is stronger than that at 595 nm. The cooperation up-conversion and the energy transfer between Yb
3+
and Eu
3+
Er
3+
and Eu
3+
lead to a strong up-conversion emission of trivalent europium ions.
