Abstract
We prepared the Y2O3 nanocrystals doped with Tm3+ and Ce3+ ions by the sol-gel method. The luminescence lifetimes, excitation and emission spectra have been studied in detail. The Tm3+/Ce3+ doped Y2O3 nanocrystals can emit strong 813â¯nm infrared with the excitation of 698â¯nm red light. The excitation wavelength at 698â¯nm and emission wavelength at 813â¯nm are located in the weak absorption area of biological tissues, which can enhance the quality of optical imaging.
