To develop a facile and general strategy for producing color-tunable, excitation-dependent, and time-dependent persistent room-temperature phosphorescence from pure organic amorphous polymers.
Grafted organic luminophores onto sodium alginate chains through amidation chemical reactions.
Fabricated amorphous polymer films and evaluated their phosphorescence emissions across varying excitation wavelengths and decay durations.
Achieved tunable afterglow emission spanning from blue to orange-red wavelengths with pronounced excitation-dependent and time-dependent characteristics.
Demonstrated that semi-rigidified polymer chains, dense hydrogen bonding networks, and oxygen barrier properties stabilize diverse emissive species with differing lifetimes.
