通过水热法简单地获得了多种形状的Eu2+掺杂硅酸钡纳米结构。通过改变溶液中Ba/Si的摩尔比，合成了刺猬状、球形、多孔不规则球形、空心蠕虫状和裂纹蠕虫壳状结构。提出了这些硅酸钡纳米结构的可能形成机制。在360nm的激发波长下，所有产品均显示出约400至625nm的宽发射带。 300 至 400 nm 的紫外区域激发带证实了纳米结构可用作白光 LED 荧光粉的可能性。
Several shapes of Eu2+-doped barium silicate nanostructures have been simply obtained by a hydrothermal method. Hedgehog-like, spherical-shaped, porous irregular spherical, hollow worm-like, and cracked worm shell-like structures are synthesized with changing the molar ratios of Ba/Si in solution. The possible formation mechanisms of these barium silicate nanostructures are proposed. Under an excitation wavelength of 360nm, all the products show broad emission bands from about 400 to 625nm. The UV region excitation band from 300 to 400nm confirms the possibility that the nanostructures could be used as phosphors for white LEDs.
