General description

Sulforhodamine G is an ambipolar fluorescent dye that is used as an acceptor dye for organic electronics. It is a water soluble and hydrophilic dye that shows an absorption peak at a wavelength of 529 nm.

Application

Sulforhodamine G can be incorporated in composites as a dye for characterizing fluorescent correlation spectroscopy based images. It can also be used in the development of an acceptor molecule that facilitates the emission of white light in a light emitting hybrid.

Nucleation and growth of hydrogen nanobubbles are key initial steps in electrochemical water splitting. These processes remain largely unexplored due to a lack of proper tools to probe the nanobubble's interfacial structure with sufficient spatial and temporal resolution. We report
