通过对泵浦光功率密度和近红外波长的调制,动态调谐上转换颜色是最方便的防伪方法。然而,大多数体上转换系统遭受对激发功率和近红外波长(980 nm和1550 nm)的不敏感响应。在此,我们证明,激发功率密度灵敏度和近红外波长灵敏度的块体微晶可以通过共掺杂Li+/Lu 3+离子得到改善。更有趣的是,具有不同价态的共掺杂离子影响在1550 nm激发下的发射颜色趋势,这与先前的报道相反。通过调节抽运功率密度和抽运波长(980 nm和1550 nm),NaYF 4:Er/Yb/Li/Lu块体微晶的发光颜色由黄色转变为明亮的绿色。此外,还系统地讨论了这一结果的机理。NaYF_4:Er/Yb/Li/Lu块体微晶的发光颜色可调谐,肉眼容易分辨,不易伪造。因此,上转换材料在透明防伪印刷中具有很好的应用前景。
Dynamic tuning upconversion color is the most convenient approach through modulation of pump power density and NIR wavelength for anti-counterfeiting. However, most of bulk upconversion systems suffer from the insensitive response to excitation power and NIR wavelength (980 nm and 1550 nm). Herein, we demonstrate that the excitation power density sensitivity and NIR wavelength sensitivity of bulk microcrystals could be improved via co-doping Li+/Lu3+ions. More interestingly, co-doping ions with different valences affect the emission color tendency at 1550 nm excitation, which is contrary to previous reports. The emission color of bulk NaYF4:Er/Yb/Li/Lu microcrystals transform from yellow to bright green color through adjusting pump power density and pump wavelength (980 nm and 1550 nm). Moreover, the mechanism of the results has been systematically discussed. The tunable emission colors of bulk NaYF4:Er/Yb/Li/Lu microcrystals can be easily distinguished with naked eyes and difficultly counterfeited. Therefore, the upconversion materials have a promising application in transparent anti-fake printing.
