    • A composite material, which can be used as an encapsulant for an ultraviolet device, is provided. The composite material includes a matrix material and at least one filler material incorporated in the matrix material that are both at least partially transparent to ultraviolet radiation of a target wavelength. The filler material includes microparticles and/or nanoparticles and can have a thermal coefficient of expansion significantly smaller than a thermal coefficient of expansion of the matrix material for relevant atmospheric conditions. The relevant atmospheric conditions can include a temperature and a pressure present during each of: a curing and a cool down process for fabrication of a device package including the composite material and normal operation of the ultraviolet device within the device package.
    • 提供了可用作紫外线装置的密封剂的复合材料。 复合材料包括基体材料和掺入基质材料中的至少部分对目标波长的紫外线辐射部分透明的填料。 填充材料包括微粒和/或纳米颗粒,并且可以具有明显小于相关大气条件下的基质材料的热膨胀系数的热膨胀系数。 相关的大气条件可以包括以下各项中存在的温度和压力:用于制造包括复合材料的器件封装的固化和冷却过程以及器件封装内的紫外线器件的正常操作。
