黃金激爆之PLED!!
利用化學合成法合成出聚苯胺及 MEH-PPV,經過一連串的製程作出高分子發光二極體(PLED),再用 I-V 儀量測。實驗中以聚苯胺及 MEH-PPV 的薄膜厚度為變因,進行實驗。 電壓值為 10V,量測樣品通路上的電流。一開始電壓在跑時,量到的電流都為 0A,所得到的圖形為一水平直線;當電壓到達一個值時會向上爬升,但爬到一個階段後圖形呈現鉛直掉落至電流為 0A,圖形又恢復成水平直線。過程中看到了薄膜厚度對樣品確實有影響,又鋁電極的厚度不能承受過大的電壓,所以,用銦粒壓在元件上藉以保護。 Using Chemiccal polymerize PANI and MEH-PPV make through a series Polymer light emitting diode(PLED)Produce.then using I-V meter surveies. PANI and MEH-PPV change of thick proces.Experiment design I-V volt for meter conduction of current of sample .The voltage moving.First meter current is obtaining the figure is horizontal when voltage increase to a special value , but increase a while , the current will fall down to zero volt. Figure will go to horizontal that sample will change .Thick is different,and aluminum cathode can not suffer too much voltage .otherwise will burn.
