Photocatalytic activity of N, S co-doped and N-doped commercial anatase TiO2 powders towards phenol oxidation and E. coli inactivation under simulated solar light irradiation.
(Pergamon-elsevier Science Ltd, 2009-10-14)
Nitrogen and sulfur co-doped and N-doped TiO2 anatase TKP 102 (Tayca) were prepared by manual grinding with thiourea and urea, respectively, and annealing at 400 C. Both materials showed visible-light absorption as measured ...
Blue upconversion enhancement by a factor of 200 in Tm 3+-doped tellurite glass by codoping with Nd 3+ ions
(2002-11-15)
We investigated near-infrared-to-blue upconversion from thulium (Tm 3+) doped in tellurite glasses upon continuous wave excitation near 800 nm. We observed an enhancement of over two orders of magnitude of the upconverted ...

Effects of strontium/lanthanum co-doping on the dielectric properties of CaCu3Ti4O12 prepared by reactive sintering
(Elsevier Ltd, 2018)
The extremely high dielectric constant of the cubic perovskite CaCu3Ti4O12 (CCTO) has attracted increasing
attention for a variety of capacitive elements in microelectronic device applications. In this research, the ...
N-doping SrTiO3@SrCO3 heterostructure electrode: Synthesis, electrochemical characterization, and varistor application
(2017-10-15)
Optical traditional techniques, such as diffusive reflectance spectroscopy, are used to confirm absorption behavior modification after anion doping process. However, the doping process in some materials as a SrTiO3 ...
