Nanocrystal multilayers on different substrates are prepared via self‐assembly of quantum dots at the air–liquid interface resulting in highly ordered solids in which each layer can be controlled for use in potential optoelectronic applications. Time‐resolved photoluminescence measurements are consistent with the theoretical picture of exciton decay in controlled stratified environment and reveal efficient energy transfer into silicon substrates.
