| 摘要: | 本研究主要使用夜光膜來探討發光方式，不同吸收能量的方式與釋放光亮之光譜分析。夜光膜到溫度50、80、100℃在數據上沒有呈現，但是在暗室實驗中還是有散發淡淡的亮光，120、140℃亮度為1 lux，160℃為2 lux的亮度， 冷光片通電30分鐘後斷電，等待5、10、20、30分鐘後進行亮度測量，會發現夜光粉之亮度相當微弱，只有約1 lux左右，在光亮處無法以肉眼觀察其發亮效果。另外，增加壓力可能無法使夜光膜中電子移動，但使用剪刀或金屬物品來剪裁夜光膜時，金屬帶走或是給予了夜光膜電子而使夜光膜發出亮光。一般光照實驗，夜光膜起始的亮度在16-18 lux之間，亮度會隨著時間遞減，平均亮度為17 lux。前5分鐘的亮度是以線性的方式減少亮度直到3 lux，之後便緩慢的下降一直到0。夜光膜也會因為吸收的能量越多而散發越多的能量因此越亮，夜光膜的發亮極限在20 lux，最後應用冷光片與一般染料布及螢光染料布L*a*b*與照度分析，為螢光黃染料濃度上升到0.3%後反射率上升100以上明度值，照度為194 lux，營光紅與螢光橘和一般染料讓明度與照度下降。
In the experiments, the luminous film did not show any data on the photometer at temperatures of 50°C, 80°C, and 100°C, however it still gave out some faint light in the darkroom. The brightness of luminous film was 1 lux when the temperatures was 120°C or 140°C, and it was 2 lux at temperatures of 160°C. After the luminescent sheet had been electrified for 30 minutes, I waited for 5, 10, 20, 30 minutes respectively to implemented measurements of brightness. I found out that brightness of the luminous powder was quite weak, only 1 lux approximately, and the effect of brightness could not be observed with the naked eye in the bright place. Moreover, increasing pressure might not be able to get the electrons in the luminescent film to move, but when scissors or metal objects were used to trim the luminescent film, the metal took away or gave the luminescent film the electrons, which made the luminescent film to shine. The initial brightness of the luminous film is between 16 lux and 18 lux in the general illumination experiments. The brightness falls scale over time, and the average brightness is 17 lux. The brightness will reduce in a linear manner in the first five minutes until it reaches 3 lux, and slowly decreases to 0 lux. In addition, the luminous film will emit more energy and become brighter when it absorbs more energy. Applying EL with dye cloth and fluorescent dye cloth L*a*b* and lux analysis, When the concentration of the fluorescent yellow dye rises to 0.3%, the reflectance increases more then 100 L*. The lux is 194 lux. Fluorescent red and fluorescent orange and dyes reduce brightness and lux. |
