    摘要: A spectrally-sensitized emulsion has been described, wherein said emulsion comprises {111} tabular silver halide grains having an average aspect ratio of at least 2 with two flat parallel {111} crystal faces accounting for a total projective surface of said parallel crystal faces in said emulsion of at least 50%, characterized in that a site-directing compound is present at said faces, satisfying the general formula I as described herein is present. A light-sensitive silver halide photographic film material comprising a support and on one or both sides thereof at least one light-sensitive emulsion layer having an emulsion as disclosed has also been described as well as a radiographic screen/film combination comprising such a light-sensitive silver halide photographic film material and a supporting or self-supporting X-ray intensifying screen, characterized in that said supported or self-supporting X-ray intensifying screen essentially consists of luminescent phosphor particles emitting green light.
