• 一般注記: 出版タイプ： NA; High-quality nanocrystalline CuBr films are fabricated by film-substrate chemical reaction of CuCl on KBr. The films exhibit more than ～104 times higher free-exciton photoluminescence (PL) efficiency at room temperature than conventional CuBr films. The room-temperature PL efficiency exceeds that of conventional CuCl films by a factor of ～103 and even the cryogenic-temperature free-exciton PL efficiency of the same films by a factor of ～102, despite the general recognition that the free-exciton PL efficiency of CuBr is much weaker than that of CuCl. The extreme PL efficiency of the CuBr is considered to be mediated by the high-quality KBr-crystal surroundings, into which and out of which Cu+ and K+ ions migrate, respectively, during the film-substrate chemical reaction, thus generating high-quality CuBr nanocrystallites in the surroundings.
