    摘要: A core-shell silver bromoiodide emulsion having an inner core portion consisting essentially of silver bromoiodide and an outer shell portion consisting essentially of silver bromoiodide, wherein said inner core portion has a silver iodide content ranging from 30 to 50 mol %, said outer shell portion has a silver iodide content ranging from 1 to 10 mol %, and the average total silver iodide content ranges from 5 to 12 mol %, and wherein the ratio between the area of the X-ray diffraction peak corresponding to said outer shell portion and the area of the X-ray diffraction peak corresponding to said inner core portion is higher than 9:1.
