Optical down-conversion in doped ZnSe:Tb3+ nanocrystals.
Rare earth (RE) Tb(3+)-doped high quality ZnSe nanocrystals (NCs) were synthesized by a facile chemical hot-injection method. ZnSe:Tb(3+) nanocrystals exhibited broadband absorption below the first excitonic absorption peak. Photoluminescence spectra showed Tb(3+) emission lines in the visible spectral window at room temperature when excited by UV radiation below the band-edge of the host ZnSe ...
متن کاملUp and Down Frequency-Conversion Properties of Eu3+ Doped Lead Fluorophosphate Nanoglass Ceramics
Europium doped transparent lead fluorophosphate glass ceramics successfully were prepared with heat treatment of precourse glasses at temperature above glass transition (Tg). X-ray diffraction (XRD) experiment evidenced the formation of PbF2 nanocrystals in glassy matrix. The emission spectra investigation indicate that considerable amount of Eu3+ ions were trapped in crystalline phase, and the...
متن کاملSpatial-to-spectral mapping in spontaneous parametric down-conversion
We put forward an approach for manipulating the spectral profile of entangled photon pairs. Such spectral properties are mediated by the geometry of noncollinear spontaneous parametric down-conversion and by selecting the appropriate spatial profile of the pump laser radiation. We show that one can translate spatial features imprinted in the pump beam into desired spectral profiles of the gener...
متن کاملSpatio-spectral characteristics of parametric down-conversion in waveguide arrays
High dimensional quantum states are of fundamental interest for quantum information processing. They give access to large Hilbert spaces and, in turn, enable the encoding of quantum information on multiple modes. One method to create such quantum states is parametric down-conversion (PDC) in waveguide arrays (WGAs) which allows for the creation of highly entangled photon pairs in controlled, ea...
متن کاملStrong Spectral Entanglement in Spontaneous Parametric Down-Conversion
Photon pairs with a high degree of spectral entanglement have a very large capacity for carrying information. We describe methods for generating this type of entanglement and discuss applications. ! 2009 Optical Society of America OCIS codes: (270.5585) Quantum information and processing; (270.5565) Quantum communications. Spontaneous parametric down-conversion (SPDC) has proven to be a reliabl...
