Transparent oxide semiconductor, a-IGZO, thin films were prepared by high-vacuum RF magnetron sputtering at different working pressures. The effect of working pressure on crystal structure, surface morphology, and electrical and optical properties of the films was studied. The highest ball mobility of 17.45 cmZ-V-l.s- 1 is obtained at 0.3 Pa with annealing at 200 ℃, while the highest carrier concentration of 2.32×10^20 cm^-3 and the lowest resistivity of 0.001568 Ω.cm are obtained at 0.45 Pa with annealing. The highest transmittance of 90.9 % is obtained at 0.9 Pa with annealing treatment. A ＂blue shift＂ of UV absorption edge is observed with the increase of working press ure.

A new two-photon absorption compound, 2-{4-[（dicyanomethylidene-5,5-dimethylcyclohexl）vinyl]phenyl}imidazo[4,5- f][1,10]phenanthroline （DDVPIP）, was synthesized and characterized. The one-photon excited fluorescence （OPEF） and two- photon excited fluorescence （TPEF） of DDVP1P are sensitive to the acid/base of the solution, which are enhanced in basic solution but weakened in acidic solution. Charge-transfer （CT） states of DDVPIP were calculated through theory methods to explain its acid/ base-sensitive fluorescent properties.
