"cathodoluminescence: aim electron beam at 2D molybdenum diselenide embedded in 2D tungsten diselenide, making it emit high resolution light... larger dots give off 1 type of glow... <10 nm wide dots trap energy/ emit light with higher frequency (quantum confinement) confining excitons at interface of the 2 materials... controlling nanodot size via controlling excitons changes emitted light's color/ frequency more effectively... faster/ more secure quantum systems, energy-saving high resolution screens"
