摘      要：Here we present the assembly of novel transparent all-polymer distributed feedback(DFB)*** and highly transparent cellulose diacetate(CdA)was employed as substrate on which gratings with different periods were engraved by thermal nanoimprinting with high *** luminescent conjugated polymers(CP),poly(9,9-dioctylfluorene)(PFO),poly(9,9-dioctylfluorene-alt-benzothiadiazole)(F8BT),and a blend of F8BT and poly(3-hexylthiophene)-poly(9,9-dioctylfluorene-altbenzothiadiazole)(P3HT:F8BT)were deposited by spin coating onto the nanostructured plastic surfaces,giving rise to perpendicular single-mode lasing emission in the blue,green,and red wavelength ranges,*** lasers show linewidths below 1 nm and low thresholds(≈6μJcm^(−2) for blue and red lasing emission),comparable to other state-of-the-art lasers obtained from similar optical gain materials on rigid *** followed strategy is scalable and versatile,enabling the development of large area nanoimprinted DFB lasers(1cm^(2))on plastic,which is highly relevant for applications in various markets.
