  • Potassium- and Rubidium-Passivated Alloyed Whereas potassium complexes with bromide from the perovskite precursor solution to form thin surface passivation layers, rubidium additives favor the formation of phase-segregated micron-sized rubidium halide crystals. This tolerance to higher loadings of potassium allows us to achieve superior luminescent properties with potassium passivation.

  • Transition Element-Like Chemistry for Potassium Abstract. At high pressure the alkali metals potassium, rubidium, and cesium transform to metals that have a d 1 electron configuration, becoming transition metal-like. As a result, compounds were shown to form between potassium and the transition metal nickel.
