The paper discussed the preparation of rare earth europium complexes ultraviolet rays (UV) photochromic ink and the influences of factors, such as europium complexes using a rare earth ternary complex of Eu ion with 3-benzoylbenzoic acid and phenathrolinephen [Eu(BA)3Phen] content upon printing ink formula. In the experiment, we utilized fluorescence spectrophotometer to make quantitative deter...
Kurtin, Bierman and Yontef (1) reported on the prevention of ultraviolet erythema by iontophoresis of a solution of Pyribenzamine (N -pyridyl-N -benzyl-N -dimethylethylene diamine hydrochloride) into the skin prior to exposure to a hot quartz ultraviolet lamp. They attributed this effect to the "antihistaminic "action of Pyribenzamine in the tissues. We were able to confirm the findings of Kurt...
In x Al1-x N films were deposited on Si(100) substrate using metal-organic molecular beam epitaxy. We investigated the effect of the trimethylindium/trimethylaluminum (TMIn/TMAl) flow ratios on the structural, morphological, and optical properties of In x Al1-x N films. Surface morphologies and microstructure of the In x Al1-x N films were measured by atomic force microscopy, scanning electron ...
We have proposed an easy and controllable method to prepare highly ordered Au nanoarray by pulse alternating current deposition in anodic aluminum oxide template. Using the ultraviolet-visible-near-infrared region spectrophotometer, finite difference time domain, and Green function method, we experimentally and theoretically investigated the surface plasmon resonance, electric field distributio...
