With the aid of baffle movement, a technique named masking pretreatment and the method of vacuum deposition have been used to fabricate the ag - o - cs photoemissive thin films with internal field - assisted structure for the first time. the internal field - assisted photoemission characteristics of ag - o - cs thin films show that the photoelectric sensitivity is increased when the internal electric field is applied to the thin films, which indicates that the electric field has been effectively provided to the thin films by the above - mentioned internal field - assisted structure. such an enhanced photoemission is attributed to the variations in energy - band structure of ag - o - cs thin films, and which are considered to induce the lower - energy electrons to participate in the photoemission

The content of styrene was found to be dependent on the investigated grafting conditions, of which the dose rate and monomer concentration were the major conditions, and the dependence of the initial rate of grafting on the dose rate and the monomer concentration was found to be of 0. 4286 and 1. 1662 orders, respectively. the results indicate that the grafting reaction is competitive and the copolymerization and the graft - copolymerization are existing at the same time. the grafting proceeds by the so - called front mechanism in which the grafting starts at the surface of the films and moves toward the middle of the film by successive diffusion of the styrene through the grafted layers
