With annealing up to 160°, close to the Tg of the components, there is little change in the feature sizes observed by STXM,although an increase in variation of the composition is observed.With annealing above 160°C the imaged features begin to evolve in size,increasing to 225 nm in extent, alongside large changes in composition with annealing to 200°C. Comparing the evolution of morphology imaged by STXM with the change in photoluminescence quenching with annealing, we propose that phase separation first evolves via the evolution of relatively pure phases on the length scale of a few to tens of nanometres within the larger 85 nm structures. Once the length scale of compositional fluctuations exceeds 85 nm (for anneal temperatures above 160°C) the hierarchy of phase separation is lost and the subsequent morphological evolution is readily imaged by STXM.Applying the results of an exciton diffusion and quenching model, we find good agreement between the size of the domains measured by STXM (above 180°C) and the results of the model for an exciton diffusion length of 15 nm. The growth in domain size and towards purer structures has also been observed with resonant soft x-ray scattering.]]> Sat 24 Mar 2018 07:18:51 AEDT ]]> Comparative analysis of Ti₃SiC₂ and associated compounds using x-ray diffraction and x-ray photoelectron spectroscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3332 Sat 24 Mar 2018 07:18:02 AEDT ]]> A low-cost mixed fullerene acceptor blend for printed electronics https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23036 Sat 24 Mar 2018 07:13:49 AEDT ]]> Plasmonic enhancement of aqueous processed organic photovoltaics https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43928 xWO3) is a promising alternative plasmonic material to nanoparticulate gold due to its strong plasmonic resonances in both the visible and near-infrared (NIR) regions. Additional benefits include its simple production either as a bulk or a nanoparticle material at a relatively low cost. In this work, plasmonic NaxWO3 nanoparticles were introduced and mixed into the nanoparticulate zinc oxide electron transport layer of a water processed poly(3-hexylthiophene):phenyl-C61-butyric acid methyl ester (P3HT:PC61BM) nanoparticle (NP) based organic photovoltaic device (NP-OPV). The power conversion efficiency of NP-OPV devices with NaxWO3NPs added was found to improve by around 35% compared to the control devices, attributed to improved light absorption, resulting in an enhanced short circuit current and fill factor.]]> Mon 29 Jan 2024 18:51:02 AEDT ]]> Observation of diffuse scattering in scanning helium microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53224 Fri 17 Nov 2023 12:06:37 AEDT ]]> Standardizing resolution definition in scanning helium microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47356 Fri 13 Jan 2023 13:26:43 AEDT ]]>
