Abstract
We have studied the optical properties of three-dimensionally confined photon states in a spherical microcavity (the photonic dots) resonantly excited by photons emitted from semiconductor nanocrystals (the quantum dots). Glass and polymer microspheres with sizes of 2λ<R<10λ are characterized by spatially and temporally resolved micro-photoluminescence. The role of nanocrystal position and orientation is analyzed experimentally and theoretically. The emission spectra of single, bulk and hollow microspheres impregnated with CdSe quantum dots and quantum rods are investigated and the modification of the quantum dot radiative lifetime by the three-dimensional photon confinement is discussed.
