Here you will find details about the research activities developed by our group.
The Optics and Nanoscopy Group (GON) was founded in 2014 and is a research group part of the Post-graduate Programs in PHYSICS (CAPES grade 5 ) and in MATERIALS (CAPES grade 4) of the Federal University of Alagoas.
We are always interested in hearing from fellow scientists wishing to work with us or potential students wishing to study with us.
Exploring the limits of physical resolution and understanding the behavior and properties of materials at the nanoscale are the central aims of the....Read more

In this study, we report the effect of the proportion of CdSe/CdS ultrasmall quantum dots (USQDs) conjugated on reduced graphene oxide (rGO). The proposed conjugation used a bond between the hydroxyl groups of the USQDs and the carboxylic groups of the rGO. The formation of the CdSe/CdS-rGO nanocomposites was confirmed by ...."

Light scattering by disordered media is a ubiquitous effect. After passing through them, the light acquires a random phase, masking or destroying associated information. Filtering this random phase is of paramount importance to many applications, such as sensing, imaging, and optical communication, to cite a few, and it is commonly..."

In this study, we evaluated the in vitro antitumor activity of dialkylamino-1,4-naphthoquinones (1a–n) toward human glioblastoma multiforme cells (GBM02). All the derivatives inhibited GBM02 cell viability except for compounds 1a, 1b, and 1c. In contrast, compounds 1d, 1e, 1f, 1g, 1h, 1k, and 1n were the most effective ones...."

We used a direct laser writing technique to build annular waveguides inside a glassy blade. These waveguides have shown the capability of generating orbital angular momentum beams with different topological charges in the same structure. Here we demonstrate that, after choosing suitable waveguide parameters, ..."
