“Giant” Colloidal Quantum Well Heterostructures of CdSe@CdS Core@Shell Nanoplatelets from 9.5 to 17.5 Monolayers in Thickness Enabling Ultra-High Gain Lasing (Small 38/2024)

Colloidal Quantum Wells

“Giant” CdSe@CdS colloidal quantum wells having thicknesses of 9.5 to 17.5 monolayers enable ultra-high material gain coefficient reaching ∼140,000 cm⁻¹ owing to the contribution of higher energy states to the gain, their high number of states per energy, and suppressed Auger recombination. This ultra-high material gain capability offers an exceptional platform for electrically-driven colloidal thin-film lasers and in-solution lasing applications. More in article number 2309494, Hilmi Volkan Demir and co-workers.
