Abstract:
We report the strong bistability effect of multiphoton upconversion, observed at room temperature, in Yb[Formula: see text]-sensitized Tm[Formula: see text] :ZrO 2 condensed-phase nanophosphors via the efficient upconversion excitation. The sizable bistability of upconversion from a collection of excited Tm[Formula: see text] ions exhibit good controllability in polarity only by varying the density of Yb[Formula: see text] sensitizer. The polarity of bistability converts regularly from clockwise into anti-clockwise cycles as the dopant density grows from 2% to 10% Yb[Formula: see text]. The results suggest a practicable way to control bistable emission of solids at room temperature.
