The effect of an external magnetic field ( 0 1 T ) on the upconversion emission ( λ exc = 976 nm ) of Gd 2 O 3 : Er 3 + Yb 3 + nanocrystalline phosphor has been studied. Optical bistability (hysteresis behavior in the intensity of the optical emission) for different transitions of the Er 3 + ion has been observed for a complete cycle of the magnetic field between 0 and 1 T . The phosphor shows paramagnetic behavior, consistent with the presence of Gd 3 + ions, at room temperature. Interaction between induced magnetization in the Gd 2 O 3 host and the intrinsic magnetic moment of the nanosized clusters of Er 3 + and Yb 3 + ion pairs is proposed to be responsible for the hysteresis behavior.
