We report broadband downconversion from ultraviolet to near-infrared in Yb 3 + -doped oxygen-deficient Sr O Al 2 O 3 Ge O 2 glasses. Oxygen-deficient centers are introduced in germanate glasses by adding metal Al instead of corresponding oxide ( Al 2 O 3 ) . Tunable luminescence related to these defects is observed. Conversion of broadband ultraviolet light to blue-green tunable luminescence and to near-infrared emission is detected in glasses. The energy transfer efficiency increases with increasing Yb 2 O 3 concentration. The dependence of energy transfer efficiency on wavelength is also discussed.
