Highly emissive CdTe nanowires grown in a phosphate buffer solution: FLIM imaging and spectroscopic studies
(2007)
We present details on the formation and optical peroperties of CdTe nanowires, which were found to grow in a standard
phosphate-buffered solution, including micro-photoluminescence and fluorescence lifetime imaging.
Highly efficient Forster resonance energy transfer between CdTe nanocrystals and two different dye molecules
(2004)
We report highly efficient Forster resonance energy transfer between CdTe nanocrystals and two different dyes,
Rhodamine B and Oxazine, where the nanocrystals are mixed with the dyes on top of glass substrates. A faster ...
Semiconductor nanowires self-assembled from colloidal CdTe nanocrystal building blocks: optical properties and application perspectives
(2012)
Solution-based self-assembly of quasi-one-dimensional semiconductor nanostructures (nanowires) from quasi-zero-dimensional (quantum dots) colloidal nanocrystal building blocks has proven itself as a powerful and flexible ...
Enhanced coupling of electronic and photonic states in a microcavity-quantum dot system
(2005)
Spherical microcavities consisting of a dielectric material show unique optical characteristics as resonators in combination with semiconductor nanoparticles. A high quality factor results in a very narrow bandwidth of the ...
The creation and annihilation of optical vortices using cascade conical diffraction
(2011)
Internal conical diffraction produces a superposition of orthogonally polarised zero- and first-order Bessel like beams from an incident circularly polarised Gaussian beam. For right-circularly polarised light, the first-order ...
Nanojets and directional emission from symmetric photonic molecules
(2007)
Symmetric directional emission of light from multisphere
photonic molecules is experimentally shown in this work. The photonic
molecules are illuminated in the vertical direction with a defocused laser
beam. The emission ...
Generation of continuously tuneable fractional optical orbital angular momentum using internal conical diffraction
(2010)
Abstract: When a left-circularly polarised Gaussian light beam, which has
spin angular momentum (SAM) Jsp = ?? = 1? per photon, is incident along
one of the optic axes of a slab of biaxial crystal it undergoes internal ...
Symmetric photonic molecules formed from coupled microspheres
(SPIE, 2008)
Coherent coupling of optical resonances in spherical microcavities results in the formation of so called photonic molecules. The name originates from the analogy to chemical molecules. The coupled optical modes are similar ...
Conical diffraction of linearly polarised light controls the angular position of a microscopic object
(2010)
Conical diffraction of linearly polarised light in a biaxial crystal produces a beam with a crescent-shaped intensity profile. Rotation of the plane of polarisation produces the unique effect of spatially moving the ...
Highly emissive nanowires grown from CdTe nanocrystals in a phosphate buffer solution
(2005)
We present details on the CdTe nanowires formation, which were found to grow in a standard
physiological phosphate-buffered solution, including in-situ observation of growth with a confocal
microscope. The choice of ...
