High-heat-resistance composite-structure fluorescent ceramic for laser illumination and preparation method of high-heat-resistance composite-structure fluorescent ceramic
The invention relates to a high-heat-resistance composite structure fluorescent ceramic for laser illumination and a preparation method thereof, the fluorescent ceramic is of a three-layer composite structure comprising a (Re1-xCex) 3Al5O12 fluorescent layer, an nAlN-Y3Al5O12 temperature gradient layer and an AlN substrate layer from top to bottom in sequence, Re is Y or Lu, and x is greater than or equal to 0.0005 and less than or equal to 0.005; 0.1 < = n < = 0.9. The preparation method comprises the following steps: respectively preparing a (Re1-xCex) 3Al5O12 single-layer ceramic biscuit, an nAlN-Y3Al5O12 single-layer ceramic biscuit and an AlN single-layer ceramic biscuit through tape casting; sequentially laminating the three ceramic biscuits from top to bottom to form a composite structure casting sheet, and performing isostatic pressing to obtain a composite structure ceramic biscuit; and finally, sequentially carrying out glue discharging, high-temperature sintering and double-sided polishing to obtain the composite-structure fluorescent ceramic. The composite structure fluorescent ceramic obtained by the method has the advantages of good heat resistance, good thermal conductivity and high luminous efficiency.
