Single-component white light materials may create great opportunities for novel conventional lighting applications and display systems; however, their reported color rendering index (CRI) values, one of the key parameters for lighting, are less than 90, which does not satisfy the demand of color-critical upmarket applications, such as photography, cinematography, and art galleries. In this work, two semiconductive chloroplumbate (chloride anion of lead(ii)) hybrids, obtained using a new inorganic-organic hybrid strategy, show unprecedented 3-D inorganic framework structures and white-light-emitting properties with high CRI values around 90, one of which shows the highest value to date.
单组分白光材料可能为新型传统照明应用和显示系统创造巨大机遇；然而，它们所报道的显色指数（CRI）值（照明的关键参数之一）小于90，无法满足摄影、电影摄影和艺术画廊等对颜色要求苛刻的高端应用的需求。在这项工作中，通过一种新的无机-有机杂化策略获得的两种半导体氯铅酸盐（铅（II）的氯离子阴离子）杂化物，展现出前所未有的三维无机骨架结构以及白光发射特性，其CRI值约为90，其中一种的CRI值是迄今为止最高的。
