Abstract

Lead-free halide double perovskites have attracted significant attention due to various exceptional photoelectric properties. Nevertheless, there is a lack of blue and red light in plant growth, it is worthwhile to look for blue-red dual-emission phosphors with greater thermal stability and high quantum efficiency for creating light-emitting diodes (LEDs) for plant growth. By introducing Sb³⁺ and Mn²⁺ ions into Cs₂NaLuCl₆, which achieves light ranging from blue (455 nm) to red (630 nm) emission. The intensity of prepared material could maintain 70 % of 80 K at 470 K and perform good thermal stability. Additionally, the resemblance between the spectra of the prepared LEDs and the spectra of the Action Spectrum, β-Carotene, Chlorophyll a, and Chlorophyll b, was 75.8 %, 81.9 %, 79.4 %, and 94.7 % respectively, showing a good matching degree, indicating that the samples have a promising application potential in plant growth.

由热稳定的无铅卤化物双钙钛矿实现的高适应性植物栽培光源

无铅卤化物双钙钛矿因其各种优异的光电性能而备受关注。然而，植物生长中缺少蓝光和红光，寻找热稳定性和量子效率更高的蓝红双发射荧光粉来制造用于植物生长的发光二极管（led）是值得的。通过在Cs2NaLuCl6中引入Sb3+和Mn2+离子，实现了从蓝色（455nm）到红色（630nm）的发光。制备的材料在470 K时强度保持在80 K的70%，具有良好的热稳定性。此外，制备的led光谱与作用光谱β-胡萝卜素、叶绿素a和叶绿素b的光谱相似性分别为75.8%、81.9%、79.4%和94.7%，具有良好的匹配度，表明样品在植物生长中具有良好的应用潜力。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
