Advancing laser lighting: High-brightness and high-stability Ce:YAG phosphor-in-glass
The advancement of laser lighting is moving towards high-power and high-brightness applications. However, traditional phosphor-in-silicone (PiS) are unable to maintain good performance under intense optical-thermal stresses. Therefore, there is a growing focus on finding color conversion material with high thermal stability and resistance to high incident laser power (Pin). Here, we have developed a low-temperature sintered phosphor-in-glass (PiG) based on a lithium-aluminium-silicate glass system. The sintered Ce3+:Y3Al5O12 phosphor-in-glass (Ce:YAG-PiG) retains the original luminescent properties of the phosphor, exhibiting a high internal quantum efficiency (IQE = 88.3 %) and high thermal conductivity (3.33 W/(m K)). At a Pin of 6.87 W, Ce:YAG-PiG achieves a luminous flux of 1481.7 lm and luminous efficiency of 221.7 lm/W. Ce:YAG-PiG shows best illumination performance in dynamic reflective module. Furthermore, the conversion efficiency and stability of the Ce:YAG-PiG color wheel surpass those of PiS color wheel, and a Ce:YAG/Ce3+:LuAG/Eu2+:CaAlSiN3 composite PiG color wheel can produce high color rendering index white light. This work is expected to find new application prospects for PiG and further promote the development of high-power dynamic laser lighting.
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.
