The mechanism of the upconversion processes in Y6O5F8:2% Er3+/X%Yb3+ (X=3, 10, 20) microtubes has been explored. The luminescent properties of the as prepared sample is investigated by utilizing up-/downconversion, decay and time resolve spectra. The results indicate that the red and green emission are clearly competitive depending on the Yb3+ concentration. High Yb3+ concentration induces the enhancement of the energy-back-transfer (EBT), process, which leads to the quenching of green emission and enhances the red emission. So it is possible to utilize the temporal evolutions of emission bands to deeply understand the color change UC mechanisms.
