摘要

富铝尖晶石为过渡金属掺杂剂提供了多样化和可变的局部环境，有利于新型荧光粉材料的发展。本研究以富铝尖晶石Mg0.75Al2.16O4为基体，掺杂不同浓度的Mn2+，制备出半峰全宽窄为37 nm、色纯度高达89.5 %、内量子效率为80.1%、热淬强度低（425 K时发射强度为室温时的86.8%）的透明陶瓷Mg0.75Al2.16O4:5%Mn2+。制备的WLED以K2SiF6:Mn4+为红色荧光粉，mg0.75 al2.16:5% mn2 +为绿色荧光粉，InGaN芯片为蓝色器件，其色域达到美国国家电视系统委员会（NTSC）标准的112%，光效为85 lm/W。这些结果表明，mg0.75 al2.160:5% mn2 +透明陶瓷在WLED背光显示领域具有潜在的优势。

A novel green-emitting Mg0.75Al2.16O4:Mn2+ transparent ceramic phosphor for white light-emitting device

Aluminum-rich spinel provides a diverse and variable local environment for transition-metal dopants, which facilitates the development of novel phosphor materials. In this study, the aluminum-rich spinel Mg_0.75Al_2.16O₄ was used as the host for doping with different concentrations of Mn²⁺, resulting in the preparation of a transparent ceramic Mg_0.75Al_2.16O₄:5%Mn²⁺ that exhibits a narrow full-width at half-maximum of 37 nm, high color purity of 89.5 %, an internal quantum efficiency of 80.1 %, and low thermal quenching (emission intensity at 425 K is 86.8 % of that at room temperature). The prepared WLED exhibits a wide color gamut of 112 % of the National Television System Committee (NTSC) standard and a luminous efficacy of 85 lm/W while using K₂SiF₆:Mn⁴⁺ as the red phosphor, Mg_0.75Al_2.16O₄:5%Mn²⁺ as the green phosphor, and InGaN chips as the blue device. These results indicate the potential superiority of Mg_0.75Al_2.16O₄:5%Mn²⁺ transparent ceramic for WLED backlight display applications.

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.
