Overview

Demonstrates color-tunable carbon quantum dots for bioimaging, indicating promising optical applications.

Key Points

  • The aim is to synthesize carbon quantum dots (CQDs) with tunable photoluminescent properties for bioimaging applications.
  • Synthesis of blue and green CQDs using plasma solution interaction method with glucose as a carbon source.
  • Variation of plasma exposure time to control optical properties and photoluminescence.
  • Characterization of CQDs through structural and spectroscopic analyses.
  • B-CQDs emit blue light at 450 nm with a quantum yield of 21%.
  • G-CQDs emit green light at 515 nm with a quantum yield of 19%.
  • Both CQDs show excellent stability and biocompatibility, with strong fluorescence in initial bioimaging tests.
