銀奈米粒子(Ag nanoparticles)在提高生物螢光檢測的方面已有許多文獻在探討。一般而言，銀可以使分佈於其表面或其溶膠附近的螢光物質之螢光發射強度，較其處於自由態時的螢光發射強度增加許多，也就是金屬表面增強螢光效應(Metal Surface Enhanced Fluorescence)。我們希望利用銀奈米粒子此種效應，搭配YAG螢光粉達到調整色度(CIE)以及演色性(color rendering index,CRI)的目的；而我們製作光學薄膜所使用的聚二甲基矽氧烷 (polydimenthy siloxane,PDMS)，不論在表面結構的定義，以及光學的穿透率還有可撓性，都具有很大的優勢。其優勢主要在於改善出光、增加元件效率、大面積化、低成本。

Ag nanoparticles have been extensively used to raise biological fluorescence emission in many applications. Generally speaking, The fluorescence enhancement is due to strong interaction between the molecules and the Ag nanoparticles through surface plasmon resonance (SPR).
We are going to use the SPR of Ag nanoparticles to tune CIE and color rendering index (CRI) of white-light organic light emitting diodes by doping the particles with YAG fluorescence phosphor on the package layer.The polydimenthy siloxane (PDMS) was used as the host material for the package layer, which is advantageous in easily making surface structure, transparency, and the flexibility. It improves the external quantum efficiency for a large-area device with low cost.
