InAlGaN EMITTING LIGHT IN SHORT-WAVELENGTH REGION OF ULTRAVIOLET REGION, ITS MANUFACTURING METHOD AS WELL AS ULTRAVIOLET LIGHT-EMITTING ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To emit light at room temperature and with high efficiency in a short-wavelength region as an ultraviolet region at a wavelength of 360 nm or shorter. SOLUTION: The composition ratio of In is set at 2 to 20%. The composition ratio of Al is set at 10 to 90%, and the total of the composition ratios of In, Al and Ga is set so that it becomes 100%.
