白光发光二极管设计制造 我们研究制作Ultra-Violet磊芯片，并采用II-VI化合物材料，掺杂I价或III价的材料，制作了R、G、B三原色的荧光体。荧光体能将300nm至400nm的UV波段吸收并转换成白光。LED的外部以 Micro Lens来改善量子效率，预期发光效率可提升至50﹪。 Abstract After the fabrication of Ultra-Violet Chip, and doping column I or III element into the II-VI compounds, we have R, G, B three original colors fluorescence phosphorous. The mixture of these three colors can absorb the UV light from 300 nm to 400 nm and transforms it into white light. The Micro Lens covering LED is used to improve the quantum efficiency and expected to be more then 50%. 关键词：紫外光、UV光、白光发光二极管、有机金属化学气相沉积、MOCVD、荧光体、 phosphorous、透镜设计、Lenses Design
