Lanthanide doped multicolor luminescent materials have attracted extensive attention due to their advanced anti-counterfeiting properties. However, designing a simple, hard-to-copy and multicolor anti-counterfeiting strategy based on upconversion nanoparticles (UCNPs) remains a huge challenge. Herein, a strategy to modulate luminescence color by altering the mediating action of Tm3+ was proposed. As a proof of concept, the mediating action of Tm3+ was explored in NaYbF4:30%Er,1%Tm@NaYF4 by changing the doping ratio of Yb3+/Er3+/Tm3+, and red, yellow and blue luminescence was successfully obtained. Then, NaYbF4:x%Er,1%Tm@NaYF4 (x = 2, 10, 30, 50, 99), NaYbF4:x%Er@NaYF4 (x = 2, 10, 30, 50, 100) and NaYbF4:1%Tm@NaYF4:x%Er@NaYF4 (x = 2, 10, 30, 50, 100) were synthesized to further identify that the mediating action of Tm3+ was related to the doping ratio and distance between dopant ions. In addition, the luminescence color of NaYbF4:30%Er,1%Tm@NaYF4 changed from red to yellow with the increase of excitation power density. Based on the above, NaYbF4:Er,Tm@NaYF4 UCNPs show excellent performance in anti-counterfeiting of paintings, thus revealing their great potential in advanced anti-counterfeiting applications.

Tm3+ 介导的 NaYbF4:Er,Tm@NaYF4 多色发光用于高级防伪
稀土掺杂多色发光材料因其先进的防伪性能而受到广泛关注。然而，设计一种基于上转换纳米颗粒（UCNP）的简单、难以复制的多色防伪策略仍然是一个巨大的挑战。在此，提出了通过改变Tm 3+的介导作用来调节发光颜色的策略。作为概念证明，通过改变 Yb 3+ /Er 3+ /Tm 3+和红色的掺杂比，在 NaYbF 4 :30%Er,1%Tm@NaYF 4中探索了 Tm 3+的中介作用，成功获得黄色和蓝色发光。然后，NaYbF 4 : x %Er,1%Tm@NaYF 4 ( x = 2, 10, 30, 50, 99), NaYbF 4 : x %Er@NaYF 4 ( x = 2, 10, 30, 50, 100) ) 和 NaYbF 4 :1%Tm@NaYF 4 : x %Er@NaYF 4 ( x = 2, 10, 30, 50, 100) 被合成，以进一步确定 Tm 3+的介导作用与掺杂比有关和掺杂离子之间的距离。另外，随着激发功率密度的增加，NaYbF 4 :30%Er,1%Tm@NaYF 4的发光颜色由红色变为黄色。 综上所述，NaYbF 4 :Er,Tm@NaYF 4 UCNPs在绘画防伪方面表现出优异的性能，从而揭示了其在高级防伪应用中的巨大潜力。
