Triply ionized thulium/thulium--ytterbium doped/codoped TeO2-Pb3O4 (TPO) glasses have been fabricated by classical quenching method. The upconversion emission spectra in the Tm3+/Tm3+-Yb3+ doped/codoped glasses upon excitation with a diode laser lasing at ∼980 nm has been studied. Effect of the addition of the Yb3+ on the upconversion emission intensity in the visible and near infrared regions of the Tm3+ doped in TPO glass has been studied and the processes involved explored.
三价铥/铥-镱掺杂/共掺杂碲氧磷（TPO）玻璃已通过经典淬火法制备。研究了在 ∼980nm 激光二极管激发下 Tm3+/Tm3+-Yb3+掺杂/共掺杂玻璃中的上转换发射光谱。研究了 Yb3+的添加对 TPO 玻璃中 Tm3+掺杂的可见和近红外区域上转换发射强度的影响，并探讨了所涉及的过程。
