The absorption and upconversion spectra of Er3+-doped fluoride (halid e) phosphate tellurite glasses were investigated for the first time, and the upc onversion mechanisms were studied. Strong red and green upconversion luminescenc e were observed under 975nm laser diode excitation at room temperature. When PbF 2 is partially replaced by PbCl2 gradually, the intensity of red emission decreases, while the green emission intensity changes only sligh tly. When ZnF2 is replaced by 5mol% ZnCl2, both red and gr een emissions intensity are enhanced obviously.
