A highly water stable and strong upconversion (UC) luminescence NaYF<sub>4</sub>@PSI–NH nanosensor for the simultaneous and selective detection of 2,4,6-trinitrotoluene (TNT) and 2,4,6-trinitrophenol (TNP) was successfully developed. Via the 980 nm near-infrared (NIR) irradiation, these nanosensors emit strong white UC luminescence with five typical emission peaks centered at 363, 455, 475, 546, and 654 nm. The UC emission at both 363 and 546 nm was quenched by the addition of TNT; however, the ratio of luminescence intensity at 363 nm to 546 nm (<i>I</i><sub>363</sub>/<i>I</i><sub>546</sub>) had no change with the increase of TNT concentration. Meanwhile, only violet UC emission at 363 nm was dramatically quenched via the addition of TNP, ...
