摘要	An encapsulant containing nanoparticles that improve the heat and UV resistance properties of electroluminescent devices. The nanoparticles that are suspended in the encapsulant may be either oxides or non-oxides and may include SiO2, TiO2, Al2O3, ZrO2, Ti, TiB2, TiC, and TiN. The nanoparticles may range in size from 5 to 165 nm in diameter. The encapsulant containing nanoparticles may be used in an electroluminescent device by being deposited in a concave base cavity to cover a light source, such as a light-emitting diode (“LED”), positioned in the concave base cavity, and may also be applied in the form of a conformal coating that covers the light source. An electroluminescent device utilizing the encapsulant containing nanoparticles and a method of producing such a device is also provided.
其他摘要	包含纳米颗粒的密封剂，其改善电致发光器件的耐热性和抗紫外线性。悬浮在密封剂中的纳米颗粒可以是氧化物或非氧化物，并且可以包括SiO 2，TiO 2，Al 2 O 3，ZrO 2，Ti，TiB 2，TiC和TiN。纳米颗粒的直径范围可以为5至165nm。含有纳米颗粒的密封剂可以通过沉积在凹形基腔中以覆盖位于凹形基腔中的光源（例如发光二极管（“LED”））而用于电致发光器件中，并且还可以应用以覆盖光源的保形涂层的形式。还提供了一种利用含有纳米颗粒的密封剂的电致发光器件和制造这种器件的方法。
