Abstract: A method of manufacturing a light-emitting device includes a number of operations. A light-emitting element is formed. A simulation of a metasurface is performed. The metasurface is formed based on the simulation of the metasurface. The metasurface is disposed on a light-emitting side of the light-emitting element. Performing the simulation of the metasurface includes establishing a metasurface model of the metasurface, in which the metasurface model has a plurality of unit cells, and phase compensation values of the unit cells are periodically distributed with a supercell period length in a deflection direction. The phase compensation values of the unit cell are adjusted and the light source is set to simulate the multiple transmittances of the metasurface model under different phase compensation values. The phase compensation values at a peak value of transmittance are selected as process parameters of the metasurface.

Abstract: The present invention provides a method for producing silver nanoparticles by employing ethanolamine. The method of this invention can be easily operated and no organic solvent is required. Ethanolamine first reacts with copolymers of poly(styrene-co-maleic anhydride) (abbreviated as SMA) to generate polymeric polymers. The polymeric polymers then reduce silver ions to silver atoms which are dispersed in the form of silver nanoparticles. Functional groups of the polymeric polymers can chelate with silver ions and be stably compatible with water or organic solvents, whereby the silver nanoparticles can be stably dispersed without aggregation and the produced silver nanoparticles.

Abstract: An automatic scan and mark apparatus has a machine tool, a location detection module, a laser detector, an ink jet and a control computer. The machine tool has a movable module and a stage. The stage mounts and holds a specimen having a scraped surface. The control computer controls the location detection module to determine a position of the movable module, controls the laser detector to detect a surface morphology of the scraped surface in a measurement range, and activates the ink jet to eject inks on high points of the scraped surface of the specimen. Thus, the surface morphology is built automatically and high points are screened out and marked by colored ink. Manufacturer may easily redo scraping of determined high points based on the marked location on the specimen without burdensome measurement.
