Rhodamine 6G encapsuled mesoporous silica channels
(Trans Tech Publications Ltd, 2009-01-01)
We report the effect of solvent on the rhodamine 6G encapsuled into channels of mesoporous silica, synthesized by two-step process that gives intermediary stable hybrid micelles. Mesoporous materials have been obtained by ...
Radio luminescence properties of decaoctahedral BaZrO3
(Pergamon-Elsevier B.V. Ltd, 2011-01-01)
Radioluminescence (RL) emissions were obtained for the BaZrO3 self-assembled nanocrystals under decaoctahedral shape, if produced via microwave-assisted hydrothermal method. Trapped F centers created within the band gap ...
Influence Of The Qd Luminescence Quantum Yield On Photocurrent In Qd/graphene Hybrid Structures
(Spie-Int Soc Optical EngineeringBellingham, 2016)
Efficient UV-visible upconversion luminescence and thermal effects in terbium-ytterbium codoped fluorogermanate vitroceramic
(2008-06-13)
Cooperative energy-transfer upconversion luminescence in Tb 3+/Yb 3+-codoped PbGeO 3-PbF 2-CdF 2 vitroceramic and its precursor glass under resonant and off-resonance infrared excitation, is investigated. Bright UV-visible ...
Luminescent multifunctional biocellulose membranes
(2011-10-17)
Luminescent biocellulose membranes were obtained by incorporation of ethanolic solutions of the europium compounds [Eu(BTFAC)3(H2O)2], [Eu(BTFA) 3(DBSO)2], [Eu(BTFA)3(PTSO)2] and [Eu(BTFA)3(FSO)2] (BTFAC- 4,4,4-Trifluoro-1- ...
Photonic materials displaying direction modulated photoluminescence
(2019-10-01)
The simultaneous integration of a nematic liquid crystalline structure and light emission in a photonic material is attractive for designing novel optical devices. Here we describe the luminescent study of a new optical ...

Effect of reaction time on the particle size of ZnO and ZnO : Ce obtained by a sol-gel method
(Springer, 2004-01-01)
In this work particles of ZnO of size range 33-56 Angstrom were prepared by a sol-gel method. The effect of reaction time on the particle size of ZnO or ZnO:Ce was investigated by transmission electron microscopy measurements, ...
Red, green, and blue upconversion luminescence in ytterbium-sensitized praseodymium-doped lead-cadmium-germanate glass
(2004-08-17)
Blue, green, red, and near-infrared upconversion luminescence in the wavelength region of 480 - 740 nm in Pr3+/Yb3+-codoped lead-cadmium-germanate glass under 980 nm diode laser excitation, is presented. Upconversion ...
