摘要

One-dimensional Y2Zr2O7:Er3+/Ho3+ nanostructures have been successfully synthesized via a conventional electrospinning technique. Their diameters are in the range of 200–300 nm. The Y2Zr2O7:Er3+/Ho3+ nanostructures exhibit variable emissions under different excitation wavelengths. Under 377 nm excitation, the Y2Zr2O7: Er3+/Ho3+ nanostructures demonstrated dominant green emission at 545 nm. When excited at 1550 nm, the nanostructures exhibit dominant red emission at 667 nm. Under 980 nm excitation, the Y2Zr2O7:Er3+/Ho3+ nanostructures exhibit a tunable emission from green to yellow to red by varying the ratio of Er3+ to Ho3+. These results indicate their potential applications in multi-mode anti-counterfeiting and information encryption. In addition, the temperature sensing properties of the Y2Zr2O7:Er3+/Ho3+ nanostructures are also investigated. The maximum values of Sa and Sr are 0.59 K− 1 and 0.94 K− 1 at 303 K for Y2Zr2O7:0.02Er3+/0.05Ho3+, which are higher than those reported for other phosphors.
