摘　　要：利用多孔阳极氧化铝(anodicaluminumoxide,AAO)作为模板,采用准分子脉冲激光溅射方法(pulsedlaserdeposition,PLD)成功制备了光荧光材料La0.95Eu0.05BaB9O16的量子点阵,用扫描电镜表征了AAO模板和制备的量子点阵,测量了靶材和量子点阵的光荧光谱.讨论了用此方法制备的量子点阵的结构和发光特性.证明此方法可为未来制备其它材料的量子点阵开辟了一条途径.Matrix of quantum dots is fabricated using anodic aluminum oxide(AAO) template and pulsed laser deposition(PLD).The cylindrical pore array structure of AAO serves as a template for the preparation of the quantum dots.The morphology of the matrix of dots and AAO template are characterized by scanning electron microscope,the luminescence spectra of the dots and target materials are recorded by a micro-Raman spectrometer.The structure and photoluminescence of the dots are discussed,which demonstrates that one can make matrix of quantum dots by this method.It is proofed that this method can fabricate the matrix of a quantum dots of the other materials in the future.
