A smartphone-assisted colorimetric/fluorescence dual-mode sensor based on Si-CDs for highly selective and sensitive detection of Cu2.
In this study, silicon-doped carbon dots (Si-CDs) were synthesized using a one-step solvothermal method to construct a colorimetric-fluorescence dual-mode sensing platform for Cu2+ detection. The prepared Si-CDs exhibit excellent water solubility and stable optical properties, and can respond specifically to Cu2+ throu...
