Fabrication of high-optical-quality white light-emitting diodes through a semi-solidification process |
| 초록 |
White light-emitting diodes (LEDs) with a uniform illumination distribution are fabricated by a facile and innovative method, a semi-solidification process. Through a semi-solidification process, the fluorescent phosphors are evenly dispersed in the encapsulant of LEDs. Uniform dispersion of phosphors is facilitated by adopting a B-stage intermediate step during a semi-solidification process. The effect of the uniform dispersion of phosphors on the performance of white LEDs is investigated through the several characteristic analyses. This approach is effective for the performance enhancement of white LEDs including a long-term stability as well as a uniform illumination distribution. |
