Abstract
Ink for producing laser light sources. The ink is used for inkjet printing to produce laser light sources of a certain scale. The ink comprises a luminescent dye, a host material, and a solvent. The use of the ink makes it possible to produce laser light sources through inkjet printing. This provides a novel technical solution for cheap and industrial manufacturing of laser light sources and other related products through inkjet printing.
Claims12
An ink for producing a laser source comprising:
- a bovine serum albumin (BSA) aqueous solution, glycerol, a matrix material, a solvent, and a luminescent dye selected from symmetrical diphenylethylene, fluorescein sodium, and rhodamine B,
- wherein a concentration of BSA in the BSA aqueous solution is 300-1000 mg/mL, a mass ratio of the luminescent dye to BSA is 1-3%, and a volume ratio of glycerol to water is 1:1-4, and wherein the ink forms the laser source through inkjet printing.
