Influence of Gold Nanoantennas on the Photoluminescence of Silicon Nanocrystals
Photonics, 2022 We study the influence of gold nanoantennas on the photoluminescence signal of silicon nanocrystals. Unlike bulk silicon, which only exhibits low photoluminescence at room temperature due to its indirect band gap, silicon nanocrystals have the advantage ...

Control of yellow photoluminescence in AlGaN/GaN heterostructures [PDF]
Modern Electronic Materials, 2019 Photoluminescence with the peak corresponding to yellow color of the visible spectrum (so-called yellow luminescence) originates from deep levels in the GaN buffer layers of heterostructures and depends on heterostructure growth conditions.
