Description

一种波长转换器件及其制备方法 技术领域
本发明涉及一种波长转换器件，具体是涉及通过其中包含的转换材料，在适当的光源激发下产生与激发光源波长不同的特定波长或光谱的光或者辐射。

波长转换材料以荧光或磷光材料为基础，可用于转换一特定波长的光或者辐射到另外一个不同波长的光或者辐射。例如，向上转换材料，可把波长较长的光转换到更短的波长，即由红外光或X射线转换为可见光；向下转换材料，可用于转换短的光波长到更长的光波长，例如：由紫外线到可见光，由蓝光到绿光，黄光和红光等。这种波长转换已有许多技术上的应用，如三维彩色光记录/显示，照明，生物分析和标签，昆虫诱捕。
波长转换材料和激发光源的位置可以由一定的距离分开放置的。例如，在一种昆虫诱捕器件中，波长转换材料可以浸泡在液体而激发光源放置在液体之外。可以选择激发光源发出的光不吸引昆虫或猎物，而在激发波长的激发下的光转换材料发出来的光，能吸引昆虫或猎物。在美国专利申请US20080054280，詹姆斯公开了一种波长转换材料作为涂层应用在灯具的覆盖层上。然而，披露结构的荧光粉涂层由浆料涂层或喷施方法实施，不能保证涂层厚度均匀性，也不能保障能否达到所需的理想的厚度。这是因为引力运动，固化过程中液体物质流向涂层表面较低点。由于极高的荧光粉薄层浓度，光的输出对荧光粉层的厚度是非常敏感的。

所述波长转换层包括波长转换材料和粘合剂，或包括波长转换材料的混合物及粘合剂。
所述波长转换材料是荧光粉、发光材料、纳米晶或它们的复合材料，粘合剂材料在特定的光波长是透明的。
所述波长转换材料至少是上转换和/或下转换荧光粉材料，至少发射可见光或红外光，经紫外光中，x激发一射线，可见光或红外线；波长转换材料为向上转换发光材料时，光波长较长的光转换成一波长更短的光，如红外光转换成可见光；波长转换材料为一个降频转换发光材料时，由波长较短的光转换为波长较长的光，如转换X射线或紫外线到可见光和由红外光、或蓝光转换成一个波长较长的光，如绿或黄或红光、或由绿色波长转换为黄色或红色光。

 本发明的最佳实施方式
如图1所示，本发明的一种波长转换器件，图 1的波长转换器件10包括基础结构1和波长转换层2。波长转换器件10的基础结构由具有优良的光学清晰度、并在一个特定的的波长或光谱为透明的材料制成。透明的材料为玻璃、玻璃陶瓷、陶瓷、聚合物如聚四氟乙烯、聚甲基丙烯酸甲酯、聚碳酸脂和硅或聚合物复合材料一组中选出。波长转换层2填满基础结构1的顶面，并完全覆盖所述基础结构1。基础结构有一个倒截圆柱形、方形、长方形或多边形结构，并截断圆柱或圆锥形或球形形状之一的形状。基础结构还具有内在的圆柱形或长方形或截圆锥面，围沟和围槽为环绕基础结构的顶面外沟，在中间形成一个岛状结构；所述波长转换层填充在上面顶面外沟，并覆盖上述岛状结构，该结构内表面可能有圆柱形或弯曲或多边形的形状之一，形成了一个光源接收腔。基础结构外部和内部的顶面是平行的。基础结构其中一顶面之间的外部和内部顶面间的距离在中心线较短，而离开中线间距较大。基础结构的中心顶面是一个平坦的面或是具有纹理结构。基础结构的围槽为锯齿字形、圆形或长方形，它就像是由一个平面垂直于波长转换器件的垂直轴切。基础结构的外层为锯齿字形、圆形或长方形，它就像是由一个平面垂直于波长转换器件的垂直轴切。波长转换层包括波长转换材料和粘合剂。粘合剂材料在特定的光波长是透明的。其中的波长转换材料至少是上转换和/或向下转换荧光粉材料，至少发射可见光或红外光一，经紫外光中，x激发一射线，可见光或红外线的光。波长转换材料为向上转换发光材料时，光波长较长的光转换成一波长更短的光，如红外光转换成可见光；波长转换材料为一个降频转换发光材料时，由波长较短的光转换为波长较长的光，如转换X射线或紫外线到可见光和由红外光、或蓝光转换成一个波长较长的光，如绿或黄或红光、或由绿色波长转换为黄色或红色光。其中的波长转换层还含有氧化物材料或热辐射材料；该氧化物材料或热辐射材料与所述波长转换材料及粘结剂位于波长转换层上表面涂层。热辐射材料可与荧光粉材料和粘合剂可以混合使用。波长转换层是部分暴露在空气中，以加强散热。其中的波长转换层的形状与基础结构的围沟和槽形状相适应。波长转换层可以转换激发光源的波长到一个所需的特定波长的光或者辐射。其中的激发光源至少是发光二极管光源，激光光源和荧光来源之一。

波长转换器10，根据需要，通过使用不同的荧光粉材料，而无需改变整个激发光源或者结构，而可以获得不同颜色的光。
