In this article, we fabricated Ce 3+ , Yb 3+ ‐coped yttrium aluminum garnet ( YAG ) inverse opal photonic crystals by a self‐assembly technique in combination with a sol–gel method. The photonic band gap was located at 545 nm. With the influence of the photonic band gap, cooperative down‐conversion energy transfer process of Ce 3+ ‐ Yb 3+ was investigated. It is significant that the energy transfer efficiency between Ce 3+ and Yb 3+ is enhanced from 29.6% to 47.6% by suppression of the yellow spontaneous emission of Ce 3+ . The mechanisms for the influence of the photonic band gap on cooperative down‐conversion process of Ce 3+ and Yb 3+ are discussed.
