Scholarcy highlights

  • The synthesis and stabilization of blue-emitting nanoclusters are very challenging
  • Just a pH change leads to a rapid interconversion of green emitting Au nanoclusters to blue emitting ones at room temperature
  • We have developed a facile, acid-induced protocol to synthesize blue-emitting Au NCs in aqueous medium at room temperature from green-emitting ones
  • We have shown that the B-NC can be efficiently applied towards detection of Pb2+
  • This simple approach towards B-NC synthesis and its stabilization can contribute to application of this material in LEDs, bioimaging, and energy transfer
  • Any queries should be directed to the corresponding author for the article
