Enhancement of up-conversion luminescence of Y<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub>:Yb<sup>3+</sup>/Ho<sup>3+</sup> nanocrystals by incorporating Li<sup>+</sup> ions
Abstract:Tri-doped (Y 0.915 Ho 0.01 Yb 0.075 Li x ) 2 Ti 2 O 7 (x = 015.0 mol %) nanocrystals were fabricated via a facile glycine combustion approach. The crystal structure, morphology and up-conversion spectra of the as-obtained products were investigated using X-ray powder diffractometer (XRD), transmission electron microscope (TEM), spectrophotometer pumped by 980 nm diode laser, and Fourier transform infrared spectrometer. XRD results demonstrated that, owing to the flux effect of
/Ho3+ samples, the green and re… Show more
