| titleOfInvention | Chemical sensitization method of silver halide emulsion |
| abstract | The invention discloses a chemical sensitization method of silver halide emulsion. Adding a gelatin solution containing halogenated barium fluoride particles subjected to ball milling into a silver halide emulsion at a constant temperature of 45-55 ℃, wherein the adding amount of the gelatin solution isAccording to the addition of 1 x 10 per mole of silver in the silver halide emulsion ‑3 ～1×10 ‑6 And (3) stirring for 20-80 minutes according to the molar halogenated barium fluoride, and then quickly freezing and storing. The invention discloses a fluoride-halogen barium fluoride (BaFX: Eu) doped with rare earth ions for the first time 2+ ) (X ═ Cl, Br, I) as a dopant, was introduced into a silver halide emulsion to prepare a barium oxyfluoride (BaFX: eu (Eu) 2+ ) Compared with the conventional chemical sensitization of the sulfur and gold, the chemical sensitization of the silver halide emulsion after chemical sensitization can improve the light sensitivity by 2 times, and the fog is not increased. |
