Semi-conductor nanocrystal emission within polymeric microcavities for whispering gallery modes observation

This study represents a novel approach for the fabrication of resonant dielectric microdisks enabling high quality microcavities. By spinning semi-conducting quantum dots of CdSe/CdS onto the microstructures and exciting using a UV 405nm laser beam, fluorescence is observed. Finding pave the way four further investigation into the lasing effect.
