Mechanically tuning CPL emission in QD-BPLCE. a Photograph of a G-G-BPLCE film being mechanically stretched. b Reflection spectra of the G-G-BPLCE film at various strains (from 0 to 40%). c Kossel diagrams and the corresponding schematics of the G-G-BPLCE film at different strains (from 0 to 40%). d Schematic diagrams of a typical deformation of the BPI unit cell. CPL spectra (e) and glum curves (f) of G-G-BPLCE at various strains (from 0 to 40%). g Photographs of a G-G-BPLCE film at 0 and 40% strain under visible light and 365 nm irradiation with no polarizer, RCPF, and LCPF
