One-pot synthesis of poly(vinylpyrrolidone)-encapsulated color-emitting silicon quantum dots for sensitive and selective detection of 2,4,6-trinitrophenol

Water-soluble PVP-Si QDs emitting bright cyan-blue color have been easily fabricated with PVP and DAMO via the one-step hydrothermal method for TNP detection. The PVP-Si QDs show a selective fluorescence quenching toward TNP based on the combination of IFE and SQE.
