Upconversion (UC) refers to nonlinear optical processes in which the sequential absorption
of two or more photons leads to the emission of light at shorter wavelength than the …

Abstract Mit Upconversion (UC, Aufwärtskonversion) werden nichtlineare optische Prozesse
beschrieben, bei denen die aufeinander folgende Absorption von zwei oder mehr Photonen …

Er3+–Yb3+ co-doped transparent glass-ceramics with varying Er/Yb content and ratio have
been prepared. High quantum yields for up-and down-conversion luminescence by energy …
