When the stakes are doubled in a wager, a player must correctly place two consecutive bets to win, but the payout is larger. Similarly, two B sites in combination dictate the properties of A BB'X (A=monocation, X=halide) double perovskites. Correctly picking two B sites is more challenging than picking just one, as in the A B X single perovskites, but the options are greater and, we believe, the rewards are higher when the stakes are doubled. In this Minireview, we emphasize fundamental aspects of halide double perovskites to provide a foundation for interested readers to explore this extraordinary class of materials. In particular, we highlight the differences and similarities between double and single perovskites and describe how the double perovskite structure potentially offers greater control over photophysical properties.
当赌注翻倍时，玩家必须连续正确下注两次才能获胜，但赔付也更高。同样，两个B位的组合决定了ABB'X（A为单价阳离子，X为卤化物）双钙钛矿的性质。与ABX单钙钛矿中只需选择一个B位相比，正确选择两个B位更具挑战性，但选择更多，而且我们认为，当赌注翻倍时回报也更高。在这篇微型综述中，我们强调卤化物双钙钛矿的基本方面，为感兴趣的读者探索这类非凡材料提供基础。特别是，我们突出了双钙钛矿和单钙钛矿之间的异同，并描述了双钙钛矿结构如何可能对光物理性质提供更大的控制。
