Combustion synthesis and up-conversion luminescence of La2O2S:Er3+,Yb3+ nanophosphors
La2O2S:Er ,Yb nanocrystalline up-converting phosphors were synthesized by a combustion method at low temperature, using ethanol as pre-ignition fuel and thioacetamide as sulfurizing agent and organic fuel. The phosphors were characterized by powder X-ray diffractometry, scanning electron microscopy, UV/Vis/NIR spectroscopy and fluorescence spectroscopy. Pure and well-crystallized La2O2S:Er ,Yb ...
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 کاملThe Conversion Revolution: Down, Up and Sideways
Continued progress in quantum communication and optical approaches to quantum computation, requires the development of enabling technologies for photonic quantum information processing [1]. Such resources include high efficiency single photon detectors, high-fidelity single-photon sources, high brightness sources of entanglement, and multiple microsecond optical quantum memories. Here we discus...
متن کاملDown- and Up-Conversion Luminescent Nanorods
The rapidly increasing health care is now challenging the development of fluorescent biolabel materials used in diagnostics and bioanalysis such as immunoassay, fluorescence imaging and DNA or toxin detection. Due to their multicolor emission, high brightness and long lifetime, lanthanide ions based luminescent nanomaterials have tremendous promise as indicators and photon sources for numerous ...
متن کاملDynamically Tuning the Up-conversion Luminescence of Er3+/Yb3+ Co-doped Sodium Niobate Nano-crystals through Magnetic Field
In this work, we show here that the up-conversion luminescence of NaNbO3:Er(3+)/Yb(3+) nano-materials can be modulated by magnetic field and a enhancement of up-conversion intensities by a factor of about 2 for Er(3+):(4)S3/2 → (4)I15/2 obtained at 30 T and about 5.4 for Er(3+):(4)F9/2 → (4)I15/2 obtained at 20 T. The increased up-conversion luminescence are mainly interpreted in terms of the e...
