The intensity-controllable luminescence of Eu3+-doped polyimide (PI) nanoparticles by UV irradiation and thermal treatment is reported. In this system, it was observed that the luminescence intensity of Eu3+ ions increased with increasing UV irradiation time, whereas intensity decreased with the elevation of thermal treatment temperature. It was estimated that the mechanism of the above phenomena are based on a reversible change in an energy transfer probability from PI to Eu3+ due to the UV irradiation and thermal treatment.
