摘要 Intense upconversion emissions of YLiF 4∶Er 3+ synthesized by hydrothermal method were obtained. The upconversion intensity decreases with the increase of environment temperature. In different temperature, the upconversion mechanism is different. At room temperature, the green upconversion mechanism is the combination of two photon process and three photon process, and the red upconversion mechanism is two photon process.
