We prepared nanoparticles of Eu³⁺-doped polyimide (6FDA-6F, BPDA-PDA, 10FEDA-4FMPD) by reprecipitation method. Polyimide of 6FDA-6F showed unique luminescence properties. It was observed that luminescence intensity assigned to Eu³⁺ increased with increase in UV-irradiation time. In contrast, the intensity decreased with elevation of heat-treatment temperature. These results agreed with that of Eu³⁺-doped 6FDA-ODA polyimide. However, Eu³⁺-doped 10FEDA-4FMPD and BPDA-PDA polyimide did not show the unique luminescence properties. It is considered that for the energy transfer from polyimide to Eu³⁺, large energy band gap in polyimide needs.
