文摘

Zeolite NIR luminescence materials are prepared by the introduction of Bi3+ within the channels of Yb3+-exchanged zeolite. We report zeolite NIR luminescence materials with an improved NIR photoluminescence (PL). The increase of luminescence intensity is attributed to the energy transfer from Bi3+ to Yb3+. Such a luminescence hybrid material (Yb1Bix@ZL) can be used in c-Si solar cells for efficient conversion of 300–450 nm light.
