Size and shape control of the crystals as a function of the treatment parameters is discussed. Their luminescence properties are investigated and some features in the cathodoluminescence images are suggested to be related to the possible formation of a core dislocation. The waveguiding behaviour of the rods as well as whispering gallery resonances with improved Q-factor are demonstrated for hexagonal and square cross-section rods. The effect of tapering of the rods on the resonance wavelength is also studied and fitted to a theoretical model.journal articlehttp://dx.doi.org/10.1039/c3tc31195chttp://pubs.rsc.org/metadata only access538.9Transmission Electron-MicroscopyLarge-Scale SynthesisOptical-Properties.
