Síntesis de partículas luminiscentes de carbono a partir de la carbonización de Beta Vulgaris (betabel)
Resumen
Se desarrolló un método de síntesis efectivo, económico y amigable con el medio ambiente para la obtención de puntos cuánticos de carbono (CQDs) con propiedades luminiscentes mediante la carbonización de la beta vulgaris (betabel) a diferentes temperaturas y tiempos de operación, sin utilizar algún otro reactivo y empleando agua como único disolvente. Los CQDs obtenidos mostraron fluorescencia mayoritariamente en azul al ser expuestos a una lampara de radiación ultravioleta de 254 nm de longitud de onda y mediante el análisis por espectroscopia infrarroja por transformadas de Fourier se identificaron a los grupos carboxilato presentes en la superficie de las nanopartículas como los responsables de las propiedades luminiscentes a los CQDs.
