摘要

To date, color-tunable photon upconversion (UC) in a single nanocrystal (NC) still suffers from cumbersome structures. Herein, we prepared a compact two-layer NC with bright and high-purity red and green UC emission upon 980 and 1530 nm excitation, respectively. The effects of trace Tm3+ doping and inert-shell coating on the UC color and intensity were discussed. In addition, the color tuning via various dual-excitation configurations and the color stability with temperature and excitation intensity were demonstrated. The proposed UC NC, featuring compact structure and high-quality color tuning, can lower the synthesis time cost and difficulty of its kind and can find wide applications in multi-channel imaging, display devices, anti-counterfeiting, and so on.
