用氧化三辛基磷脂或烷基胺的含量和烷基化合物合成并表征wurtzite ZnO纳米晶体。这些ZnO纳米晶体可以通过从溶液中的还原物质或上述带有紫外线灯的带隙光激发的物质中掺杂的电子转移来制成N型。 N型纳米晶体表现出强烈的标映红外吸收，对带间带边缘吸收的广泛漂白以及光致发光的完全淬火。
Wurtzite ZnO nanocrystals capped with trioctylphosphine oxide or alkylamines are synthesized and characterized. These ZnO nanocrystals can be made n-type either by electron transfer doping from reducing species in solution or by above band gap photoexcitation with a UV lamp. The n-type nanocrystals exhibit a strong intraband infrared absorption, an extensive bleach of the interband band-edge absorption, and a complete quenching of the photoluminescence.
