摘要：

A series of ZnO microcrystallite films deposited on quartz substrates were annealed at the temperature of 600 similar to 1050 degrees C. A well c- axis grown wurtzite ZnO film was obtained at the annealing temperature of 850 degrees C. For the samples annealed above this temperature, the empirical parameter E-0 increased calculated from transmittance spectra, which indicated the changes of the interface of ZnO microcrystallite. Measured by Z- scans, the nonlinear absorption coefficient beta(eff) increased from 1.2 x 10(2) cm/ GW to 1.1 x 10(3) cm/ GW when the annealing temperature rose from 950 degrees C to 1050 degrees C, mainly due to the interfacial state enhancement.
