Fluorescence labeling is a very useful analytical technique for investigating the structure of live cells. Inorganic quantum dots or organic fluorescent dyes have been used in the immunofluorscence labeling due to their high quantum yield, high molar extinction coefficients, broad absorption with narrow light emission, and good photo physical and chemical stability. But, the semi-conducting quantum dots are toxic for any living cell and self-quenching of organ fluorescent molecules is critical for a steady imaging. Thus, developing highly emissive, biocompatible, and chemically readily modifiable luminescent materials is strongly desired. Here, we report the enhanced photoluminescence of nano-sized colloids with heterocyclic organic compounds for possible use in the field of immunofluorescence labeling.
