Abstract :
Yb3+–Er3+ co-doped amorphous Zn0.3Al0.25Pb0.3Li0.1−xYbyErxF2.05+2x+3y films have been prepared by pulsed-laser deposition (PLD). Violet, green, red and ultraviolet (UV) up-conversion emissions were observed under the infrared excitation at 950 nm. In comparison with the up-conversion of the target, the violet and UV emissions are enhanced greatly. The enhancement is attributed to the enrichment of Yb concentration in the sample during PLD.
