Inorganic-organic hybrid luminescent materials have received great attention for their potential applications in a wide range of clean/renewable energy-related areas, including photovoltaics and solid-state lighting. Herein, we present a unique and general "Mn + Cu" approach by blending two earth-abundant luminogenic metals, manganese and copper, within a single ionic structure to construct a remarkable family of low-cost and multifunctional hybrid materials featuring dual emission, as well as triboluminescence and second-harmonic generation response. The novel hybrid materials are made of diphosphine dioxide-chelated [Mn(O∧O)] cations and various anionic [CuI] clusters, ensuring manifestation of dual phosphorescence streamed from octahedral Mn ions (605-648 nm) and iodocuprate anions (480-728 nm). Noteworthily, the relative ratio of the emission bands, and hence a resulting emission chromaticity, can be tuned in a wide range through modification of cluster [CuI] modules. The structural diversity, enhanced robustness, and up to 100% luminescence quantum yield make the designed materials promising phosphors for lighting and sensing applications.
无机-有机杂化发光材料因其在包括光伏和固态照明在内的广泛清洁/可再生能源相关领域的潜在应用而备受关注。在此，我们提出了一种独特且通用的“Mn + Cu”方法，即将两种储量丰富的发光金属锰和铜混合在单一离子结构中，构建出一类低成本且多功能的杂化材料家族，其具有双发射以及摩擦发光和二次谐波产生响应。这些新型杂化材料由二膦二氧化物螯合的[Mn(O∧O)]阳离子和各种阴离子[CuI]簇组成，确保了八面体Mn离子（605 - 648 nm）和碘铜酸盐阴离子（480 - 728 nm）产生的双磷光得以显现。值得注意的是，通过修饰簇[CuI]模块，可以在很宽的范围内调节发射带的相对比例，进而调节发射色度。结构多样性、增强的稳定性以及高达100%的发光量子产率使所设计的材料成为用于照明和传感应用的有前景的磷光体。
