Abstract

Truly fluorescent excitation-dependent carbon dots are prepared, and the relationship between their chemical composition and fluorescent emission is discussed. Furthermore, potential applications of the as-prepared carbon dots to multicolor bio-labeling and multidimodal sensing are demonstrated.

Keywords: carbon dots; cellular imaging; fluorescent excitation-dependence; full-color emission; multidimensional sensing.
