Abstract: A fiber-type electronic device comprising a pattern for electronic devices stacked on a fiber filament substrate is provided. It is possible to manufacture an electronic device directly on a fiber filament substrate by applying the pattern for electronic devices. Thus, it can be widely used for wearable devices and the like. The pattern for electronic devices is manufactured by a method for forming a pattern for electronic devices comprising an exposure process using a maskless exposure apparatus. Thus, it is possible to manufacture a pattern for electronic devices on a fiber filament substrate through a continuous process and thus to increase the process efficiency.

Abstract: Provided are nitrogen-doped carbon quantum dots as pyrolysis product of fumaronitrile. The carbon quantum dots may be formed in such a manner that nitrogen may be doped in an amount of 3-10 wt % based on the total weight of the carbon quantum dots with no need for a separate doping process. As a result, the carbon quantum dots have excellent properties, such as optical property, electroconductivity and thermal safety, and thus may be useful for photocatalysts or organic solar cells, or the like.
