WebAug 1, 2024 · It can be seen that the as-prepared Cr: ZnS particles are of bimodal size distributions. The smaller particles are less than 100 nm, which is similar to the crystlline size calculated from XRD results. However, the larger ones are about 200–500 nm, which is much larger than the calculated crystlline size. Webdemonstrated in Cr:ZnS with a view to power scaling chromium laser technology utilizing the thermo-mechanical advantages of Cr:ZnS over alternative transition metal doped II-VI semiconductor laser materials.
