Abstract

Dynamic luminescence materials overcome the disadvantage of traditional static anti-counterfeiting materials that are easy to imitate, but the repeated display of dynamic luminescence is still a challenge. In this work, the dynamic luminescence material Sr3Ga4O9: Sm3+ was synthesized. It was found that under 254 nm irradiation, the color of PL gradually changed from purple to pink in tens of seconds. More importantly, the dynamic luminescence intensity and self-recovery performance of the phosphor were improved by doping Zn2+. The experimental results show that this is achieved by Zn2+ acting as a new dynamic luminescence center and enhancing the density of the shallow trap. In addition, multi-color secondary dynamic luminescence, which used in the field of anti-counterfeiting, was experimentally demonstrated. This study provides a new perspective on the synergistic enhancement of dynamic luminescence intensity and rapid self-recovery.

增强 Zn2+ 共掺杂 Sr3Ga4O9: Sm3+ 的动态发光和自恢复性能
动态发光材料克服了传统静态防伪材料易于仿制的缺点,但动态发光的重复显示仍是一个难题。本研究合成了 Sr3Ga4O9: Sm3+ 动态发光材料。研究发现,在 254 纳米波长的照射下,PL 的颜色在数十秒内从紫色逐渐变为粉红色。更重要的是,通过掺杂 Zn2+ 提高了荧光粉的动态发光强度和自恢复性能。实验结果表明,这是由于 Zn2+ 充当了新的动态发光中心,并提高了浅阱的密度。此外,实验还证明了用于防伪领域的多色二次动态发光。这项研究为动态发光强度的协同增强和快速自我恢复提供了一个新的视角。
