[Study of achieving white organic LED by fluorescence dye].
Some hybrid organic LEDs are made by using fluorescence dye and InGaN blue-light chip and the possibility of achieving white organic LED is investigated according to light conversion theory. Firstly, the LEDs made by normal method and double-dotting glue method are studied. It is found that the double-dotting glue method is too complex and the LEDs made by this way is low-luminance, so it isn't fit to make LED. Secondly the different weight ratio of 1/1/100, 1/1/200, 2/1.5/100 ax-17/zq-13/AB LEDs are manufactured. The 2/1.5/100 LED's color coordinate is (0.32, 0.30), approaching to white point and the correlative color temperature is 6290K which is close to sunlight. So it is a relatively ideal white lamp-house.
