| Abstract |
Carbon Quantum Dots (CQDs) have gained prominence in recent years due to their unique optical and chemical properties, making them valuable in a wide range of applications, including forensics. This study presents the hydrothermal synthesis of CQDs from Cassia bakeriana Craib
leaves, a readily available and sustainable precursor. The resulting CQDs were characterized for
their morphological, structural, and optical properties. The hydrothermal method involved the
extraction of leaf material and subsequent carbonization in a controlled high-temperature and high pressure environment. Fourier-transform infrared (FTIR) spectroscopy confirmed the presence of functional groups on the CQDs' surfaces. The optical properties of the CQDs were evaluated using
UV-Vis absorption and photoluminescence (PL) spectroscopy. The CQDs displayed strong and
tunable fluorescence emission, with excitation-dependent behavior. This property makes them
suitable for various forensic applications, including latent fingerprint detection. The synthesized CQDs from Cassia bakeriana Craib leaves hold promise for use in forensic science due to their eco-friendly and cost-effective production method, as well as their excellent optical properties. |
