Extended Data Fig. 1: Higher energy lines associated with the 580-590 nm emitters.

From: Revealing multiple classes of stable quantum emitters in hexagonal boron nitride with correlated optical and electron microscopy

Extended Data Fig. 1

a, HAADF and decomposed CL spectral weight maps of the emitter with ZPL at 578 nm in Fig. 4a of main text. b, CL spectral components showing higher energy peaks similar to that in Fig. 2a. c, HAADF and CL spectral weight maps of the emitter E6 in Fig. 3a with ZPL at 590 nm. d, CL spectral components for emitter in (c). Each pixel in the CL weight maps is 15 nm. For both emitters here, the PL spectrum has two probable phonon-sidebands, a similar spectral signature to the emitter in the main text Fig. 2a. All these three emitters have four higher energy (UV-blue) peaks in their CL spectrum. For the particular emitter in panels (c-d), spectral decomposition shows that the 420 nm emitter is located 80 nm away from the 590 nm emitter. However, the 460 nm, 500 nm and 532 nm peaks are localized to the same 15 nm bright pixel as the 590 nm peak.
