摘 要: | Emission enhancement at 2.7 μm is observed in Er^3+/Pr^3+--codoped germanate glasses when pumped by a 980-nm laser diode. Significant reductions in 1.5-μm emission and upeonversion intensity indicate efficient energy transfer between Er^3+ and Pr^3+; the energy transfer efficiency is as high as 77.4%. The mechanisms of energy transfer are discussed in detail. The calculated emission cross-section of Er^3+/Pr^3+- codoped germanate glass is 8.44× 10 ^-21 cm^2, which suggests that Er^3+/Pr^3+-codoped germanate glass can be used to achieve efficient 2.7-μm emission.
