Journal Article
Marshall, A. R. L., Roberts, M., Gierschner, J., Bouillard, J. G., & Adawi, A. M. (2019). Probing the molecular orientation of a single conjugated polymer via nano-gap SERS. ACS applied polymer materials, 1(5), 1175-1180. https://doi.org/10.1021/acsapm.9b00180

Determining the molecular orientation at the single molecule level is of key importance for a wide range of applica-tions ranging from molecular electronic devices to biomedical applications. In this work Surface-Enhanced Raman Scattering (SERS) was... Read More about Probing the molecular orientation of a single conjugated polymer via nano-gap SERS.

Light emission enhancement using randomly distributed plasmonic nanoparticle arrays (2014)
Journal Article
Butkus, J., Edwards, A. P., Quacquarelli, F. P., & Adawi, A. M. (2014). Light emission enhancement using randomly distributed plasmonic nanoparticle arrays. Optical materials, 36(9), 1502-1505 . https://doi.org/10.1016/j.optmat.2014.04.010

We have fabricated and characterised the optical properties of solution processed randomly distributed gold nanoparticle plasmonic arrays that are coated with a thin-film fluorescent dye. Three times enhancement in the emission intensity of the fluor... Read More about Light emission enhancement using randomly distributed plasmonic nanoparticle arrays.

Plasmonic nanogaps for broadband and large spontaneous emission rate enhancement (2014)
Journal Article

We present the optical properties of a plasmonic nanogap formed between a silver metallic nanoparticle and an extended silver film that shows a strong enhancement in the spontaneous emission rate over the whole visible range. In particular, we use th... Read More about Plasmonic nanogaps for broadband and large spontaneous emission rate enhancement.
