  "id": "MLC-T-CHM-010575",
  "term": "Schiller layers",
  "field": "Chemistry",
  "definition": "Iridescent, ordered layers that form in certain colloidal suspensions containing anisometric particles, such as flat plates or rods. The regular, parallel arrangement of these particles at high concentrations creates a structure that acts as a diffraction grating for visible light. The observed colors, which change with the angle of illumination and viewing, result from the constructive interference of light scattered by these periodic structures.",
