Description
本出願は、2012年1月19日に出願された米国仮出願第61/588,377号の利益を主張し、その内容の全ては、引用を以って、本明細書の一部となる。
一般的な20mwLEDパッケージのサイズの成形ナノ粒子蛍光体を、モールドとして、実際のLEDパッケージを用いて作製した。トルエンのCFQD溶液(例えば、20mg無機)を、真空下で乾燥して、QD残留物を残した。残留物について、ラウリルメタクリレート(1.85ml、6.6mmol)を、架橋剤トリメチロールプロパントリメタクリレート(1.06ml、3.3mmol)に溶解した光開始剤(イルガキュア 819、9mg)の溶液に加えた。モノマー混合物のアリコート(1.5乃至3ul)を用いて、LEDのカップを満した。次に、充填されたLEDに光を照射した(HamamatsuUV―LEDランプLC―L2、365nm、7500mW/cm2、3分)。そして、凝固した成形ナノ粒子蛍光体を、単純に叩いてLEDから取り除いて、次に、(例えば、原子層堆積―ALDなどのコーティング方法、又はPVOH等の高遮断材料を用いて)気体遮断フィルムでコーティングした。次に、コーティングされたディスクを、適当な封入用樹脂で満たされた新たなLEDパッケージに装着した。
