Resumen:
|
Indium oxide microcrystals with shapes of truncated cubes and pyramids as well as microrods with square, triangular or hexagonal cross-sections are grown by a catalyst free evaporation deposition method. 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.
