Abstract Films of TiO 2, La-doped TiO 2 (La–TiO 2), La–TiO 2/TiO 2 and TiO 2/La–TiO 2 are
prepared by sol-gel (dip coating) route. The structural properties like phase, grain size …

A deep understanding of the effect of the A‐site cation cross‐exchange on the hot‐carrier
relaxation dynamics in perovskite quantum dots (PQDs) has profound implications on the …
