We analyzed the interaction of three materials, reduced graphene oxide (RGO), [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), and poly(3-hexylthiphene) (P3HT), as well as the dependence of its photophysical properties within the temperature range

Aims: This work investigates the photoluminescence properties of poly(3- octylthiophene), namely P3OT films, under excitation power and time light expositions. When exposed to monochromatic illumination, the degradation mechanism of P3OT films is pre

In this paper, we report a simple procedure to decouple effects from temperature and volume on the emission properties of thin films of poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene-vinylene] (MEH-PPV). This procedure consists of applying a posit

Female mimicry by males is a widespread phenomenon in several taxa and may be involved in aggression avoidance or facilitated access to resources. In early developmental stages, female mimicry may be a mechanism involved in signalling sexual immaturi
