Title: Upconversion and pump saturation mechanisms in Er{sup 3+}/Yb{sup 3+} co-doped Y{sub 2}Ti{sub 2}O{sub 7} nanocrystals

Abstract

The Er{sup 3+}/Yb{sup 3+} co-doped Y{sub 2}Ti{sub 2}O{sub 7} nanocrystals were synthesized by the sol–gel method. X-ray diffraction, transmission electronic microscopy, and photoluminescence spectra were measured to verify the Y{sub 2}Ti{sub 2}O{sub 7} nanocrystalline produced in the sample annealed at 800 °C. The anomalous slopes of the fitted line in the log-log plots for upconversion emissions and the pump-saturation effect of near-infrared emission were observed in the nanocrystalline samples. A theoretical model of practical Er{sup 3+}/Yb{sup 3+} co-doped system based on the rate equations were put forward and explained the experimental phenomena well.
