采用光固化快速成型和连续烧结法制备了具有金刚石结构的陶瓷光子晶体。通过立体平版印刷形成掺入10体积% TiO 2-SiO 2的环氧树脂的绿色体，然后在空气中在1100 ℃-1400 ℃下加热2小时。烧结产物保持金刚石结构，具有约57%的线收缩率和38%的孔隙率。具有8个单胞的陶瓷光子晶体在中心频率为23.5GHz处显示出光子带隙。这种三维（3D）陶瓷光子晶体的制造方法适用于其他3D结构陶瓷，并且不需要任何成型技术。
Ceramic photonic crystals with diamond structure were fabricated using stereolithography and successive sintering. The green body of an epoxy resin incorporating 10 vol% TiO2- SiO2 was formed by stereolithography and then heated in air at 1100 degrees-1400 degrees C for 2 h. The sintered products maintained the diamond structure with a linear shrinkage ratio of about 57% and a porosity of 38%. The ceramic photonic crystal with eight unit cells showed a photonic band gap at the center frequency of 23.5 GHz. This fabrication method of three-dimensional (3D) ceramic photonic crystals is applicable to other 3D structural ceramics and does not require any molding techniques.
