我们在这里展示了水热合成方法，通过简单地调节溶液的pH值来可控地制备胶体γ-AlOOH纳米棒和纳米球。这些纳米晶体在煅烧条件下进一步转化为γ-Al 2 O3纳米棒和纳米片。结果表明，所制备的γ-Al 2 O3纳米棒和纳米片在室温下具有较强的光致发光性能。目前的纳米晶具有独特的尺寸和形状特征，可能会在许多领域开辟有前途的应用。(C)2007爱思唯尔有限公司保留所有权利。
We demonstrated here the hydrothermal synthetic method to controllably prepare colloidal gamma-AlOOH nanorods and nanollakes by simply adjusting the pH value in the solution. These nanocrystals were further converted into gamma-Al2O3 nanorods and nanoflakes under calcining conditions. It is found that the as-prepared gamma-Al2O3 nanorods and nanoflakes can exhibit strong photoluminescent properties at room temperature. The present nanocrystals with distinctive size and shape features might open up promising applications in many fields. (C) 2007 Elsevier Ltd. All rights reserved.
