Description

Manganese sulfide nanoparticle sensitizer and its production and use
Technical field
The invention belongs to the photosensitive silve halide material technical field, particularly a kind of manganese sulfide nanoparticle sensitizer and its production and use.
Background technology
The sensitizing of silver halide microcrystal emulsion mainly contains chemical sensitization and spectral sensitization two classes.The purpose of chemical sensitization mainly is to improve the light sensitivity of silver halide microcrystal in its intrinsic spectral absorption region, and the purpose of spectral sensitization mainly is to increase the light sensitivity of silver halide microcrystal in its extrinsic spectral absorption region.
By chemical sensitization processes such as sulphur sensitizing, golden sensitizing, sulfur plus gold sensitizing, the silver halide microcrystal surface has the chemical sensitization spot of certain size with formation, i.e. silver sulfide spot or silver sulfide gold spot.Under the irradiation of light, produce light induced electron and hole in the silver halide microcrystal, the main effect of sensitization spot is exactly the light induced electron or the hole of capturing in the silver halide microcrystal, and wherein light induced electron forms latent image and time latent image by certain photochemistry.
If many chemical sensitization spots are contained on a silver halide microcrystal surface, electronics that illumination is produced in crystallite and hole might be captured by these sensitization spots respectively.Could form a latent image owing to need several light induced electrons to combine at least with the activity of developing with the gap silver ion, therefore the breaking up of the branch of sensitization spot diminishes the probability of single sensitization spot trapped electron, the probability that causes generating latent image diminishes, the dispersion that is the sensitization spot may cause latent image to disperse, light sensitivity reduces, and contrast also reduces.In order to improve light sensitivity, increase contrast, except that the size of control sensitization spot size, also to make the sensitization spot concentrated relatively, preferably have only a sensitization spot on a microcrystal grain, can only form a latent image.
The chemical sensitizer that common chemical sensitization method is adopted mainly is water miscible sulphur, gold compound, as the sulphur sensitizer sodium thiosulfate, thiocarbamide etc. is arranged, and golden sensitizer has the complex compound of golden salt, gold etc.But these water-soluble sensitizers are added in the emulsion, and significant disadvantages is that the absorption position on the silver halide microcrystal surface relatively disperses, and the sensitization spot position of generation relatively disperses, thereby cause latent image to disperse.Therefore, how to make the chemical sensitization spot concentrated relatively in the distribution on silver halide microcrystal surface, more effectively improve light-sensitive silver halide degree and contrast, be the target that people seek assiduously always.
United States Patent (USP) 5604084 has been introduced the chemical sensitization method of sulfocompounds such as thiocarbonate, thiocarbamide, thioether; United States Patent (USP) 5167875 has been described a kind of preparation method of silver sulfide colloidal sol, is used for the development layer of silver halide microcrystal emulsion sensitizing or silver salt diffusion transfer; United States Patent (USP) 5362470 has prepared a kind of ultra-fine silver, golden sulfide, is used for silver halide microcrystal emulsion sensitizing, compares with the process for increasing sensitivity of routine, and the light sensitivity of its emulsion increases, and photographic fog reduces; United States Patent (USP) 5759760 has been introduced the solids sensitizer of several water-dispersion types, and they are made up of water insoluble and gold compound, tellurium compound, palladium compound organic solvent respectively; United States Patent (USP) 6100621 has been introduced the sensibilization of the potpourri of a kind of glutaraldehyde sulphite and selenium compound.
The sensitizing mode of above sensitizer mainly can be divided into two classes.One class is that compound is adsorbed on the silver halide microcrystal surface with molecular state earlier, passes through a series of physics and chemical change then, forms the chemical sensitization spot.Because the activity site on silver halide microcrystal surface is a lot, might form many sensitization spots at a particle surface, and the size heterogeneity of sensitization spot, certainly will cause latent image to disperse like this, light sensitivity is difficult for improving.Another kind of be the particulate of water dispersible attached to the silver halide microcrystal particle surface, form the chemical sensitization spot.But such water dispersible particulate is not easy and chemical reaction takes place for silver halide microcrystal surface, or is subjected to the influence of other material in the emulsion and can not be adsorbed on the silver halide particle surface effectively, because of rather than a kind of effective chemical sensitizer.
Summary of the invention
