A new CdTe@SiO2@CdSe nanohybrid was demonstrated for the ratiometric fluorescence detection of Cd2+via the turn-on model and “ion-imprinting” technique.
In this work, silicon doped graphene quantum dots (Si-GQDs) were prepared and applied for the sensitive and selective fluorescence detection of triclosan (TCS) in combination with Ru3+ ions.
