Ceramic-glass ceramic thin film composite structure fluorescent color wheel for white light LD illumination and preparation method of ceramic-glass ceramic thin film composite structure fluorescent color wheel
The invention discloses a ceramic-glass ceramic film composite structure fluorescent color wheel for white light LD (laser diode) illumination and a preparation method thereof. The ceramic-glass ceramic film composite structure fluorescent color wheel comprises a transparent ceramic substrate and a double-color fluorescent glass ceramic film, the double-color fluorescent glass ceramic film is of a composite structure composed of a cyan light-emitting fluorescent glass ceramic film and an orange-red light-emitting fluorescent glass ceramic film, and each of the cyan light-emitting fluorescent glass ceramic film and the orange-red light-emitting fluorescent glass ceramic film is a composite phase composed of Al2O3 and Mg2Al4Si4O16: xEu < 2 + >. The preparation method comprises the following steps: carrying out dry pressing molding and sintering on Al2O3 powder to obtain a transparent ceramic substrate; eu < 2 + > ions are doped with Mg2Al4Si4O16, red light emission is realized through one-step crystallization, cyan light emission is realized through two-step crystallization, Al2O3 is added as a scattering center, and the fluorescent color wheel is obtained through sintering. The fluorescent color wheel obtained through the method can effectively supplement cyan light and red light components, photon reabsorption caused by mixing of fluorescent materials is avoided, and the fluorescent color wheel has excellent heat dissipation capacity and good light uniformity.
本发明公开了一种用于白光LD照明的陶瓷‑玻璃陶瓷薄膜复合结构荧光色轮及其制备方法，包括透明陶瓷衬底及双色荧光玻璃陶瓷薄膜，双色荧光玻璃陶瓷薄膜为由青光发光荧光玻璃陶瓷薄膜和橙红光发光荧光玻璃陶瓷薄膜组成的复合结构，均由Al2O3和Mg2Al4Si4O16：xEu2+组成的复合相。制备方法：将Al2O3粉体通过干压成型、烧结获得透明陶瓷衬底；采用Eu2+离子掺杂Mg2Al4Si4O16，通过一步晶化实现红光发射，两步晶化实现青光发射，并添加Al2O3作为散射中心，烧结得到荧光色轮。该方法所得到的荧光色轮可有效补充青光和红光成分，避免荧光材料混合造成的光子重吸收，具有优异的散热能力和良好的光均匀性。
