Nanophosphors: PL, EL, and biological markers

초록

Phosphors whose particle size is about 2 to 3 nm (called Quantum dots or Qdots) have very unusual properties. Quantum states and confinement of their excitons may shift their absorption and emission energies. Such effects are important for tuning their luminescence stimulated by photons (photoluminescence-PL) or electric fields (electroluminescence-EL). CdS:Mn/ZnS Qdots were synthesized using a microemulsion process. Procedures for functionalizing Qdots and their use as markers in biological systems were described. PH4 - 3
