本實驗利用混摻方式將單一有機綠光摻雜物10-(2-benzothiazolyl
)- 1,1,7,7-tetramethyl-2,3,6,7-tetrahydro-1H,5H, 11Hbe nzo[l]-pyrano [6,7,8-ij] quinol izin-11-one(C545T)和其他的物質依照不同比例混合，
利用其曝光前後性質的改變以單一材料製成兩種不同的薄膜元件L1 -（紅色）和L2 （綠 色），藉由調整發光光色及L1/L2之膜厚濃度比而達到預期之光色或CIE值。將兩種薄膜元件結合並利用藍色背光源激發薄膜上的材料，實驗結果顯示為可調變式光源，特製白光光源，屬於光色轉換薄膜(Color-change materials)。

In this thesis , we studied a green emitter (C545T) dopanted SU8. C545T is an organic dye.
[10-(2-benzothiazolyl)-1,1,7,7-tetramethyl-2,3,6,7-tetrahydro-1H,5H,11Hbenzo[l]-pyrano[6,7,8-ij]quinolizin-11one(C545T)] .
When the sample of C545T and SU8 with thin films were exposured to UV-light. We found that the thin film between with UV exposure (L1-Red) and without UV exposure (L2-Green) will show the different chemistry properties.We can achieve proper CIE coordinates and color by adjusting .The different concentrations of C545T dopanted in SU8 thin films.The L1 and L2 were close-kint blue back-light in order to achieve a tunable emission module . If we crafted meticulously optimization , we can find a exclusive
white light. This is a optic thin film attach to Color-change materials
