摘要
We developed a simple and efficient nanoimprinting technique based on the capillary force lithography to fabricate two-dimensional arrays of nanoholes on the surface of poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) layers. A replicated polymer mold was used as the imprinting stamp, and the surface nanopatterns were formed by capillary rise of the moist PEDOT: PSS solution. The nanopatterned PEDOT: PSS layer could refract the incident light, thereby increasing the path lengths of the light passing through the zinc phthalocyanine (ZnPc) films deposited on the PEDOT: PSS layer. As a result, the absorbance of the ZnPc films was enhanced by up to similar to 14% in parts of the absorbance range of ZnPc. (C) 2013 Elsevier B. V. All rights reserved.
