UV-patternable polymers with selective spectral response

► The negative photoresist Epocore is doped by three commercially-available with the purpose to obtain a selective absorbance filters. ► The structures of dye-doped Epocore are fabricated by a standard UVphotolithographic process. ► The structurability of the dye-doped Epocore is retained with a reduction of the resolution as the dose increases. ► The spectral response of the dye-doped Epocore filters shows a selective passbands and stopbands. ► After the bleaching study, the dye-doped Epocore shows a high photostability retaining 96% of its filtering ability.
