Evaluación de la luminiscencia de puntos cuánticos de carbono sintetizados mediante el método hidrotermal a partir de triticum Evaluation of the luminescence of carbon quantum dots synthetized through the hydrothermal method from triticum ResumenEn el presente trabajo se realizó la síntesis de puntos cuánticos a partir de Trigo (Triticum) por el método hidrotermal, optimizando las condiciones de síntesis para el control de la emisión y composición de la superficie para su potencial aplicación como biomarcador. Los puntos cuánticos de carbono obtenidos, fueron caracterizados mediante las técnicas de espectroscopia de luminiscencia, obteniendo una excitación máxima a los 371 nm y una emisión máxima en los 442 nm emitiendo un color azul-cian dentro del rango visible que fue comprobado por el sistema de coordenadas cromáticas, por espectroscopia UV-Vis se presentan transiciones electrónicas π-π* y n-π*, así como el cálculo de Egap con valores de 1.61 y 2.13 eV. Finalmente, la espectroscopia FT-IR, nos muestra grupos funcionales como OH-, C-H, C-N, C=C, C-O, C-OH, C-O-C, COOH, C=C, lo que permite la formación de puntos cuánticos funcionalizados para la fabricación de biomarcadores. Palabras Clave:Puntos cuánticos, tratamiento hidrotermal, luminiscencia. AbstractIn the present work, the synthesis of carbon quantum dots from Wheat (Triticum) was carried out by the hydrothermal method, optimizing the synthesis conditions for the control of the emission and composition of the surface for its potential application as a biomarker. The carbon quantum dots obtained were characterized by luminescence spectroscopy techniques, obtaining a maximum excitation at 371 nm and a maximum emission at 442 nm emitting a blue-cyan color within the visible range that was verified by the system of Chromatic coordinates, electron transitions π-π * and n-π * are presented by UV-Vis spectroscopy, as well as the calculation of Egap with values of 1.61 and 2.13 eV. Finally, FT-IR spectroscopy shows functional groups such as OH-, CH, CN, C = C, CO, C-OH, COC, COOH, C = C, which allows the formation of functionalized carbon quantum dots for manufacturing of biomarkers.
