By controlling the molar ratio of Ag to HAuCl4路4H2O, the extinction peak of resultant can be continuously tuned from the blue to the near infrared sections for both absorption and scatting. The results of UV-vis, XRD, TEM, and SEM show the different characters on the Ag and Ag@Au ...

The contamination of melts from crucibles could be avoided by the rotating crucible method, with which it became possible to measure the solubility of Ag2O for the Na2O–B2O3 system above the melting point of Ag for the first time. It was found that the addition of Na2O decreases the ...
