The absorption, excitation, emission spectra and upconversion luminescence of Er: Tm: NaY (WO4) 2 were measured at room temperature. The results of the calculations were calculated using the JO theory. The results show that Er: Tm: NaY (WO4) 2, the special energy transfer and related up-conversion between Tm and Er ions have been reported, and the energy level transitions between the ions have been explained. At the same time, the properties of Er enhanced Tm emission near infrared Fully researched
