Embodiment 1
[0027] Weigh 39.8336 g of ZnS powder and 0.1664 g of MgO powder according to the molar ratio ZnS:MgO=99:1, mix them, add 24 g of deionized water and ball mill for 4 hours, and then vacuum dry at 110°C for 8 hours. Add 2 grams of deionized water to the dried powder, grind and stir thoroughly, and then press it into a circular green sheet with a diameter of 27.5 mm and a thickness of 2.5 mm. The blank is put into a crucible and placed in a vacuum tube furnace, and 5.0000 grams of powder with the same composition and 0.5000 grams of high-purity sulfur powder are placed around it. The vacuum tube furnace was evacuated to 0.1 Pa, and then high-purity nitrogen was introduced. Under a protective atmosphere, the temperature of the tube furnace was raised to 1100° C. and kept for 5 hours, and then naturally cooled to room temperature to obtain the desired ceramic target. The ceramic material was used as the laser ablation target material, and the substrate was ultrasonically cleaned f...
Embodiment 2
[0030] Weigh 38.9714 g of ZnS powder and 1.0286 g of MgO powder according to the molar ratio ZnS:MgO=94:6, mix them, add 24 g of deionized water and ball mill for 4 hours, and then vacuum dry at 110°C for 7 hours. Add 2 grams of deionized water to the dried powder, grind and stir thoroughly, and then press it into a circular blank with a diameter of 27.5 mm and a thickness of 2 mm. The blank is put into a crucible and placed in a vacuum tube furnace, and 5.000 grams of powder with the same composition and 1.1000 grams of high-purity sulfur powder are placed around it. The vacuum tube furnace was evacuated to 0.1 Pa, and then high-purity nitrogen was introduced. Under a protective atmosphere, the temperature of the tube furnace was raised to 1250° C. and kept for 4 hours, and then naturally cooled to room temperature to obtain the desired ceramic target. The ceramic material was used as the laser ablation target, and the substrate was ultrasonically cleaned for 15 minutes with...
Embodiment 3
[0033]Weigh 35.1545 grams of ZnS powder and 4.8455 grams of MgO powder according to the molar ratio ZnS:MgO=75:25, mix and add 24 grams of deionized water to ball mill for 4 hours, and then vacuum dry at 110°C for 8 hours. Add 2 grams of deionized water to the dried powder, grind and stir thoroughly, and then press it into a circular blank with a diameter of 27.5 mm and a thickness of 3 mm. The blank is put into a crucible and placed in a vacuum tube furnace, and 5.0000 grams of powder with the same composition and 2.0000 grams of high-purity sulfur powder are placed around it. The vacuum tube furnace was evacuated to 0.1 Pa, and then high-purity nitrogen was introduced. Under a protective atmosphere, the temperature of the tube furnace was raised to 750° C. and kept for 6 hours, and then naturally cooled to room temperature to obtain the desired ceramic target. The ceramic material was used as the laser ablation target material, and the substrate was ultrasonically cleaned f...
