摘要

Ultralong sodium alginate-based phosphorescent materials with room-/high-temperature phosphorescence

multicolor tunability

and flexibility were prepared by doping with 1

4-naphthalenedicarboxylic acid and Rhodamine B

demonstrating potential for flexible displays and information encryption.

Abstract

Room/high-temperature phosphorescence materials have broad application prospects in advanced anti-counterfeiting

flexible displays

and wearable electronic devices. In this study

sodium alginate (SA)-based room/high-temperature phosphorescence materials with multicolor luminescence were prepared by doping 1

4-naphthalenedic

arboxylic acid (1

4-H

NDC) and the fluorescent dye rhodamine B (RhB) into the SA matrix. The SA-1

4-H

NDC system exhibited a yellow-green afterglow lasting 4 s

with an ultralong phosphorescence lifetime of 358 ms under ambient conditions. The ternary system SA-1

4-H

NDC-RhB was constructed using SA-1

4-H

NDC as the energy donor and RhB as the energy acceptor

and phosphorescence emission in the long-wavelength region was achieved. SA-1

4-H

NDC-RhB showed concentration- and time-dependent afterglow color tunability

via

triplet-to-singlet Förster resonance energy transfer. Notably

the phosphorescences of SA-1

4-H

NDC and SA-1

4-H

NDC-RhB both exhibited heat resistance in the temperature range of 25−80 °C. Large-area flexible SA-1

4-H

NDC and SA-1

4-H

NDC-RhB films were conveniently fabricated using the solution-blending-coating-drying process. Owing to their excellent mechanical and optical properties

flexible SA-1

4-H

NDC and SA-1

4-H

NDC-RhB films were successfully applied in flexible displays and information encryption.
