Aloe vera derived carbon dots as multifunctional fluorescent probe for temperature, pH, and ferric ion sensing.

ABSTRACT: Carbon dots (CDs) synthesized from natural precursors with excellent fluorescent properties are drawing a lot of attention for sensing and biosensing applications. We offer a sustainable carbon precursor derived from Aloe vera gel, utilizing a green one-step hydrothermal synthesis of carbon dots. A systematic optimization of the synthesis parameters was conducted by varying the reaction temperature, ranging from 180 °C to 240 °C in a 20 °C interval, while adjusting the reaction duration (4, 8, 12, and 16 h). We studied the absorption and emission of the prepared CDs using optical characterizations, such as UV-Vis and photoluminescence spectroscopy. X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier transform infrared (FTIR) spectroscopy were used to study the stru
