High-thermal-conductivity heterostructure near-infrared fluorescent ceramic, preparation method and application of high-thermal-conductivity heterostructure near-infrared fluorescent ceramic in near-infrared detection of grain quality
The invention discloses a high-thermal-conductivity heterostructure near-infrared fluorescent ceramic as well as a preparation method and application thereof. The high-thermal-conductivity heterostructure near-infrared fluorescent ceramic is periodically arranged square grid skeleton heterostructure fluorescent ceramic, and the periodically arranged square grid skeleton heterostructure fluorescent ceramic is utilized to solve the problems that heat transfer and fluorescence efficiency of a ceramic body are difficult to consider, light beams are disorderly refracted and thermally induced fracture is caused. The preparation method comprises the following steps: preparing a ceramic biscuit by combining a photocuring 3D printing technology with a gel technology: printing gel-state slurry with a component X into periodically arranged square grid skeleton ceramics, and introducing near-infrared fluorescent ceramic slurry with a component Y into microscopic gaps of the square grid skeleton ceramics, and the periodically arranged square grid skeleton heterogeneous fluorescent ceramics are constructed. High absorption efficiency, high heat conduction and high light extraction efficiency can be achieved through the periodically-arranged square grid framework structure heterogeneous fluorescent ceramic, and the fluorescent ceramic and a blue laser/LED chip excitation source are packaged and then widely applied to the fields of illumination and grain quality near-infrared detection.
本发明公开了一种高导热异质结构近红外荧光陶瓷及其制备方法与应用。所述高导热异质结构近红外荧光陶瓷为周期性排布的正方形网格骨架异质荧光陶瓷，利用周期性排布的正方形网格骨架结构异质荧光陶瓷解决陶瓷体的传热和荧光效率难以兼顾、光束无序折射和热致断裂的问题。采用光固化3D打印技术结合凝胶技术制备陶瓷素坯：将成份为X的凝胶态浆料打印成周期性排布的正方形网格骨架陶瓷，在正方形网格骨架陶瓷的微观空隙内引入成份为Y的近红外荧光陶瓷浆料，构建周期性排布的正方形网格骨架异质荧光陶瓷。周期性排布的正方形网格骨架结构异质荧光陶瓷可实现高吸收效率、高导热和高光提取效率，将该荧光陶瓷与蓝光激光/LED芯片激发源封装后广泛应用于照明与粮食品质近红外检测领域。
