Ag nanoparticle decorated graphene oxide: Fluorescence quenching and surface enhanced raman scattering
Mc Cabe, Eithne; Bradley, Louise; Blau, Werner (2016)The emission and Raman scattering properties of three dyes, Rhodamine 6G (R6G), Rhodamine B (RhB) and Sulforhodamine 101 (SR101), were characterised on graphene oxide (GO) and Ag nanoparticle (NP) decorated graphene oxide ... -
Bacterially synthesized tellurium nanostructures for broadband ultrafast nonlinear optical applications
Blau, Werner; Zhang, Hongzhou (2019)Elementary tellurium is currently of great interest as an element with potential promise in nano-technology applications because of the recent discovery regarding its three two-dimensional phases and the existence of Weyl ... -
Broadband saturable absorption and exciton-exciton annihilation in MoSe2 composite thin films
Blau, Werner; Wang, Gaozhong; Baker-Murray, Aidan A.; Zhang, Xiaoyan; Bennett, Daniel; Wang, Jing Jing; Wang, Jun; Wang, Kangpeng (2019)Polyvinyl alcohol (PVA) was utilized as a matrix to host two-dimensional (2D) liquid-phase-exfoliated MoSe2 nanosheets. These 2D MoSe2/PVA composite thin films were experimentally proven to be preferable for efficient ... -
Controllable Charge-Transfer Mechanism at Push-Pull Porphyrin/Nanocarbon Interfaces
Blau, Werner; Senge, Mathias; Apraçay, Pinar; Maity, Partha; Meindl, Alina; Plunkett, Shane; Akca, Sevilay; Mohammed, Omar F. (2019)Ultrafast charge transfer at the interfaces between 5,15-donor-acceptor push-pull porphyrins (Por-tBu and Por-OC8) and nanocarbon materials in the form of fullerene (C60) and graphene carboxylate (GC) are investigated ... -
Influence of graphene oxide/Ag nanoparticle composites on the fluorescence properties of organic dyes
Bradley, Louise; Blau, Werner (2017)Graphene oxide/Ag nanoparticle (AgGO) composite materials have been proposed for surface enhanced Raman scattering (SERS) detection of fluorescent dye molecules. In this study we examine the role of the different components ... -
Two-Photon Absorption in Monolayer MXenes
Nicolosi, Valeria; Blau, Werner (2020)Two‐photon absorption (2PA) is a nonlinear optical (NLO) effect that typically occurs in a conventional semiconductor whose bandgap is larger than the energy of one excited photon but smaller than the energy of two photons. ...
