Synthesis of photoluminescent carbogenic dots using mesoporous silica spheres as nanoreactors.
A novel and facile approach for preparing hydrophilic carbogenic dots (CDs) has been developed with mesoporous silica spheres as nanoreactors by using an impregnation method. The resulting highly efficient photoluminescent CDs without any further treatment are monodisperse, photostable and of low toxicity, and show excellent luminescence properties.
