【Abstract】 The Inorganic-organic hybrid nano particles with Keggin or Dawson structure [(CH 3) 4N] 3PW 12 O 40 ·6H 2O(Ⅰ),[(CH 3) 4N] 6P 2Mo 18 O 62 ·9H 2O(Ⅱ), 2·SiW 12 O 40 ·7H 2O(Ⅲ) were prepared by solid-state reaction at room temperature. Their structure, particle sizes and appearances were characterized with elemental analyses IR, XRD and TEM techniques. The sizes are in the range of 4～8 nm. We also found the potential charge-transfer and nonlinear optical properties of them.更多还原
