Chemistry in Pictures: Fluorescence

May 3, 2018

Chunks of stuff and stuff in beakers glow bright colors.

Colloidal quantum dots incorporated in ionic salts (bottom, NaCl matrix) are more brightly photoluminescent than they are in solution (top, aqueous). Changing quantum dot size and/or composition yields different emission colors, allowing device makers to tune the optical properties of the material.
