1. a kind of preparation method of the electrum rice structure with regulatable plasma resonance absorption characteristic, its feature existsIn comprising the following steps:

  • (1) silver-colored rice sol solution is prepared with silver nitrate, polyvinylpyrrolidone, Macrogol 600;

    (2) gold and silver displacement reaction:

    The silver-colored rice sol solution prepared is cleaned after centrifugation with absolute ethyl alcohol and deionized water, plus goneThe scattered silver-colored rice colloidal sol of ionized water, then adds polyvinylpyrrolidone, is maintained under the conditions of 80~100 DEG C, gold chloride water is added dropwiseSolution, reaction, which is finished, produces electrum rice structure;

    Wherein, gold chloride;

    The mol ratio of silver nitrate is 1~6;

    500.
