Defects in a lattice structure of hexagonal boron nitride can be detected with photoluminescence

Defects in a lattice structure of hexagonal boron nitride can be detected with photoluminescence. Researchers shine a light with a color or energy on the material and get a different color from the defect. In addition, the figure shows hydrogen bubbles being generated from these defects that contain catalyst atoms (gray and dark spheres attached to the vacancies).
