Despite limited research on rare earth-doped double perovskites, leveraging their ultrahigh luminous efficiency to achieve bright yellow LED emission and addressing energy transfer challenges between Yb 3+ and Nd 3+ ions in double perovskite La 2 ZnTiO 6 with moderate phonon energy are explored in this work.

Lead-free CsCu 2 I 3 perovskites are promising luminescent materials with strong optical performance and environmental stability, but the fundamental origins of their emission polarization remain unclear, particularly whether the intrinsic polarization of self-trapped excitons (STEs) can be maintained.
