Responses of the modified TOFs (MTOFs) to methylene blue (MB) solution and surrounding refractive index (RI) have been compared. The higher-order modes are effectively filtered by the silica nanospheres  which is visualized by the interferometric output spectrum of the MTOF. The higher-order mode filtering makes the MTOF respond to MB solution with reduced sensitivity  which endows the MTOF with the potential for distinguishing the RI property from the absorption property of the molecules under detection. 2013 Optical Society of America.   Studies of the optical band positions, spin-Hamiltonian parameters and defect structure for Cr3+ in CdIn2S4 crystal 期刊论文  OAI收割 Optical Materials, 2013, 卷号: 35, 期号: 6, 页码: 1261-1263 W.

Iodine is dissolved in transparent benzene to make solution of I2 in benzene  and the absorption coefficients of the solution are measured at certain wavelengths. The absorption curve can be divided into non-resonance absorption region  pre-resonance absorption region  strict resonance absorption region  and post-resonance absorption region respectively. Resonance absorption Raman scattering experiments are conducted by a 532 nm frequency-doubled Nd:YVO4 laser  and the wavelength is in the strict resonance absorption region of solution of I2 in benzene. Compared with I2  the absorption of benzene can be neglected. Non-resonance Raman scattering of the solution is performed using a 632.8 nm He-Ne laser  and no spectrum lines of I2 are found. The study demonstrates that there is one spectrum line of I2 in the Raman scattering spectrum in the I 2 liquid-core optical fiber  but this line is not found in the spectrum of the non-resonance and resonance absorption Raman scattering of I2 solution in benzene using absorption cell. The experiments proved that I 2 Raman scattering  is greatly enhanced by using both resonance absorption and liquid-core optical fiber.   Theoretical studies of the optical spectrum band positions and spin-Hamiltonian parameters for VO(2+) ions in MgNH(4)PO(6)center dot 6H(2)O crystal from three microscopic methods 期刊论文  OAI收割 Physica B-Condensed Matter, 2008, 卷号: 403, 期号: 23-24, 页码: 4171-4173 W.
