	The investigation of point defect modes of phononic crystal for high Q resonance (EI CONFERENCE) 会议论文 OAI收割 2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, TRANSDUCERS'11, June 5, 2011 - June 9, 2011, Beijing, China 作者: Liu J.; Liu J. 收藏 \| 浏览/下载：21/0 \| 提交时间：2013/03/25 Point defect cavity was constructed in a two-dimensional phononic crystal plate. It was excited by a small piezo chip in the cavity and the vibration of each point defect modes were detected by an optical interferometer. Point defect modes on 2D PC plate in vacuum air and loaded with water were investigated theoretically and experimentally to make clear of Q factors which are affected by inner attenuation band gap effects and medium. The way to get high Q resonance has been found. It helps to design a new kind of resonator or sensor. 2011 IEEE.
	Ion beam sputter deposition of zirconia thin films (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photoelectronic Detection and Imaging, ISPDI 2007: Optoelectronic System Design, Manufacturing, and Testings, September 9, 2007 - September 12, 2007, Beijing, China 作者: Liu L.; Yang H.; Liu L. 收藏 \| 浏览/下载：21/0 \| 提交时间：2013/03/25 We determined the optical constants (the refractive index n and the extinction coefficient k) of ion beam sputter deposited zirconia thin films with spectroscopic ellipsometry (SE). First we obtained the structure information (the layer thickness surface roughness and layer diffusion) by fitting the grazing x-ray reflection (GXRR) spectra. The fitted surface roughness is verified by atomic force micrometer (AFM) measurement. Second based on the acquired structure information the measured ellipsometry spectra are fitted in the range of 240-800nm at an incident angle of 70.25 degree. The optical constants are solved based on the Tauc-Lorentz dispersion. The optical band gap extracted by SE is 4.79eV. Finally the optical band gap is verified by Taue plot method which is well consistent with that of SE.

We get the relation between the band gap width and the number of the layers the dielectric indices contrast the center wavelength. The microcavity of 1-D PC is made. We study the reflection and transmission characteristics of the microcavity. Experimental results indicate the microcavity of 1-D PC can get a high reflection coefficient and a good stability and substantiality of the membrane layers in air.
	Spectroscopic investigations of Er3+ doped Bi2O 3 -B2O3 -SiO2 glass (EI CONFERENCE) 会议论文 OAI收割 ICO20: Materials and Nanostructures, August 21, 2005 - August 26, 2005, Changchun, China 作者: Chen B.; Wang X.; Wang X.; Wang X.; Wang C. 收藏 \| 浏览/下载：75/0 \| 提交时间：2013/03/25 From the optical absorption measurements the Judd-Ofelt parameters were computed using Judd-Ofelt theory. According to the radiative lifetime obtained from the Judd-Ofelt parameters and the measured lifetime the 1.5m quantum efficiency was calculated. The quenching effect of OH upon the lifetime of 1.5m emission was investigated. From the absorption sideband measurement of glass host the value of optical band gap was estimated. The McCumber theory was used to calculate the stimulated emission cross-section and in approximate agreement with experimental one if the emission spectrum could be obtained accurately. The gain coefficient spectra were computed.
