In the Present paper, the microstructure of diamond - like a - C: H: N films was studied by analysis of transmission - reflection and infrared spectra. The experimental results showed that the content of N - H group increased and the content of C - H group de-creased with N2/Ar gas flow rate ratios increasing in a - C: H: N films. The conducting process of a - C: H: N films was discussed accord-ing to the dependence of electrical conductivity on temperature in the range 77~300K. The densities of the states at...

In the Present paper, the microstructure of diamond - like a - C: H: N films was studied by analysis of transmission - reflection and infrared spectra. The experimental results showed that the content of N - H group increased and the content of C - H group de-creased with N2/Ar gas flow rate ratios increasing in a - C: H: N films. The conducting process of a - C: H: N films was discussed accord-ing to the dependence of electrical conductivity on temperature in the range 77~300K. The densities of the states at the Fermi energy level were estimated.

The structure, excitation and emission spectra of photoluminescence of γ-Bi2WO6:Pr3+ prepared by solid state reaction were studied, the diffusion reflection spectrum of γ-Bi2WO6 was recorded. The density Dx=9.53 g/cm3 and crystal parameters α=5.45A, b=16.42A, and c=5.43Aof γ-Bi2WO6:Pr3+ were measured.

The structure, excitation and emission spectra of photoluminescence of γ-Bi2WO6:Pr3+ prepared by solid state reaction were studied, the diffusion reflection spectrum of γ-Bi2WO6 was recorded. The density Dx=9.53 g/cm3 and crystal parameters α=5.45A, b=16.42A, and c=5.43Aof γ-Bi2WO6:Pr3+ were measured. The main peaks of its photoluminescence spectrum are 600, 608 and 611, 629nm, which are from 1D2→3H4, 3Po →H6, 3Po→3H6 and 3Po→3F2 transitions of Pr3+, respectively The excitation spectrum of γ-Bi2WO6:Pr3+ consists of the main excitation band with maximum 372nm and 450nm peak. The diffusion reflection spectrum indicates that there has strong absorption in the range of 225-430nm, at the same time, the main excitation bands of excitation spectra of γ-Bi2WO6:Pr3+ and γ-Bi2WO6 are similar, which indicates that the main excitation band of γ-Bi2WO6:Pr3+ is from the host possibly due to the transition absorption of band-to-band, charge transfer transition of W-O and defect level transitions. The 450nm peak is from characteristic absorption 3H4→3P2 of Pr3+. The favorite dosage of Pr3+ in BWO:Pr3+ is about 0.8mol%.

Quantum sized Titania and SnO 2 doped Titania were prepared by Sol Gel method. After heat treatment at different temperatures, powder samples with different sizes (3~12 nm) were obtained. These samples were characterized with X-ray diffraction, eletron diffraction and reflect spectrum. Experiment shows that doped SnO 2 promotes the anatase →rutile phase transformation process, and reduced the temperature of phase transition. The doped SnO 2 restrain the growth of nano crystals of TiO 2. Quantum size effect of nano Titana was observed. But shift of optical absorption edge was not so apparent when concentration of SnO 2 changed. Probable reasons were discussed.
