Abstract
⺠Film of amorphous Y2O3:Tm3+, Yb3+ is prepared by ns pulsed laser irradiation. ⺠The film present strong blue upconversion emission. ⺠The relative intensity of the blue emission to the infrared one is an order of magnitude higher than that of the bulk material. ⺠The enhancement of the blue upconversion is attributed to the longer lifetime of the levels of the doped ions.
