Abstract
Carbon dots (CD) produced through chemical sources need a passivation agent, unlike those created from natural sources. These CD have a vivid luminescence, mainly in the blue spectrum, which can be used in various fields of science and engineering. In this study, we have utilized the widely available Allamanda cathartica flowers to produce CD through solvothermal process. The resulting CD exhibited excellent optical properties with a fluorescence lifetime of 4.71 ns and an average particle size of 3.23 nm. The CD were utilized as co-sensitizers in a dye-sensitized solar cell with N719 dye which showed four times more efficiency than the only CD-sensitized device.
