A Sr0.95Al2O4∶0.02Eu2+, 0.03Dy3+ phosphor was synthesized via co-precipitation with ultrasound assistance and subsequently sintering at 1 200℃ for 3 h. The effect of ultrasonic time on the qualities of the precursors and the phosphors as well as the photoluminescent/mechanoluminescent properties of the phosphors was analyzed by laser particle size analysis, specific surface area measurement, X-ray diffraction, scanning electron microscopy, plasma emission spectroscopy, and spectrophotometry, respectively. The results show that the ultrasound in co-precipitation process can improve the crystallinity of crystalline, and increase the actual doping amount of Eu2+/Dy3+ ions in the phosphors. Compared to the phosphor synthesized in the absence of ultrasound, the photoluminescent intensity and mechanoluminescent intensity excited by impacting on the sample of phosphor synthesized in the presence of ultrasound for 40 min can be increased by 45.67% and 148.73%, respectively. This is possibly due to the improved crystallinity and the increased actual doping amount of Eu2+/Dy3+ ions in the phosphor. Furthermore, the mechnoluminescent mechanism of Sr0.95Al2O4∶0.02Eu2+, 0.03Dy3+ phosphor synthesized with respect to the effect of ultrasonic assistance was also discussed.

采用超声波辅助化学共沉淀法制备前驱体,并在煅烧温度1 200℃和保温时间3 h条件下,合成了Sr0.95Al2O4∶0.02Eu2+,0.03Dy3+荧光粉。采用激光粒度仪、比表面积仪、X射线衍射仪、扫描电子显微镜、等离子体发射光谱仪和光分光光度计分析了超声波辅助时间对共沉淀法所合成前驱体以及经煅烧后荧光粉的品质和光致/力致发光性能的影响。结果表明:在共沉淀合成过程中,采用超声波辅助手段可改善所合成荧光粉产品中晶体结晶度和增加荧光粉晶体结构中Eu2+/Dy3+离子的实际掺入量。与未经超声波辅助所合成的样品相比,经超声波辅助所合成荧光粉的光致发光强度和经冲击激发的力致发光强度可分别提高45.67%和148.73%,这主要归因于荧光粉中晶体结晶度的改善以及Eu2+/Dy3+的实际掺入量增加所致。此外,还探讨了超声波辅助对改善所合成荧光粉的力致发光性能的影响机制。

采用超声波辅助化学共沉淀法制备前驱体,并在煅烧温度1 200℃和保温时间3 h条件下,合成了Sr0.95Al2O4∶0.02Eu2+,0.03Dy3+荧光粉。采用激光粒度仪、比表面积仪、X射线衍射仪、扫描电子显微镜、等离子体发射光谱仪和光分光光度计分析了超声波辅助时间对共沉淀法所合成前驱体以及经煅烧后荧光粉的品质和光致/力致发光性能的影响。结果表明:在共沉淀合成过程中,采用超声波辅助手段可改善所合成荧光粉产品中晶体结晶度和增加荧光粉晶体结构中Eu2+/Dy3+离子的实际掺入量。与未经超声波辅助所合成的样品相比,经超声波辅助所合成荧光粉的光致发光强度和经冲击激发的力致发光强度可分别提高45.67%和148.73%,这主要归因于荧光粉中晶体结晶度的改善以及Eu2+/Dy3+的实际掺入量增加所致。此外,还探讨了超声波辅助对改善所合成荧光粉的力致发光性能的影响机制。

A Sr0.95Al2O4∶0.02Eu2+, 0.03Dy3+ phosphor was synthesized via co-precipitation with ultrasound assistance and subsequently sintering at 1 200℃ for 3 h. The effect of ultrasonic time on the qualities of the precursors and the phosphors as well as the photoluminescent/mechanoluminescent properties of the phosphors was analyzed by laser particle size analysis, specific surface area measurement, X-ray diffraction, scanning electron microscopy, plasma emission spectroscopy, and spectrophotometry, respectively. The results show that the ultrasound in co-precipitation process can improve the crystallinity of crystalline, and increase the actual doping amount of Eu2+/Dy3+ ions in the phosphors. Compared to the phosphor synthesized in the absence of ultrasound, the photoluminescent intensity and mechanoluminescent intensity excited by impacting on the sample of phosphor synthesized in the presence of ultrasound for 40 min can be increased by 45.67% and 148.73%, respectively. This is possibly due to the improved crystallinity and the increased actual doping amount of Eu2+/Dy3+ ions in the phosphor. Furthermore, the mechnoluminescent mechanism of Sr0.95Al2O4∶0.02Eu2+, 0.03Dy3+ phosphor synthesized with respect to the effect of ultrasonic assistance was also discussed.
