Researchers have revealed more details about omnidirectional photoluminescence (ODPL) spectroscopy - a method for probing semiconducting crystals with light to detect defects and impurities. Tohoku ...
(a) A scheme of temperature variable ODPL spectroscopy. The spectra of ODPL and SPL as well as r (ODPL intensity divided by SPL intensity) measured at (b) T = 300 K and (c) T = 12 K. (Image: Kazunobu ...
