Abstract Herein, we fabricated flexible and transparent textured graphene films based on reduced graphene oxide flakes on polyethylene terephthalate substrates using a spray coating technique and investigated their photoresponsivity over a broadband range of wavelengths from the ultraviolet to infrared regions. The fabricated films exhibited a broadband photoresponse, with responsivity values reaching 2.5 mA/W at 365 nm, 2.4 mA/W at 530 nm, and 1.7 mA/W at 940 nm. In addition, the photoresponsivity was studied under bending deformation. Our flexible and textured reduced graphene oxide films could maintain a stable photoresponse upon bending for the radii of curvature larger than ~ 0.35 cm with a photocurrent deviation of

柔性纹理还原氧化石墨烯薄膜的宽带光响应

摘要在此，我们使用喷涂技术在聚对苯二甲酸乙二醇酯基材上制备了基于还原氧化石墨烯薄片的柔性透明纹理石墨烯薄膜，并研究了它们在从紫外到红外区域的宽带波长范围内的光响应性。制造的薄膜表现出宽带光响应，响应度值在 365 nm 处达到 2.5 mA/W，在 530 nm 处达到 2.4 mA/W，在 940 nm 处达到 1.7 mA/W。此外，还研究了弯曲变形下的光响应性。我们的柔性和纹理化还原氧化石墨烯薄膜可以在弯曲曲率半径大于 0.35 cm 时保持稳定的光响应，光电流偏差为
