Fig. 2: Optical and physical properties of GaN NWs decorated with/without Ru nanoparticles.

From: Utilizing full-spectrum sunlight for ammonia decomposition to hydrogen over GaN nanowires-supported Ru nanoparticles on silicon

Fig. 2

A PL spectroscopy of GaN NWs/Si decorated with/without Ru NPs recorded with pulse excitation of 80 MHz at a wavelength of 325 nm. B TRPL spectroscopy of GaN NWs decorated with/without Ru NPs by a time-correlated single photon counting technique. τavr: average charge lifetime. C Infrared thermal images of Ru NPs/GaN NWs/Si, GaN NWs/Si, Ru NPs/Si, and Ru NPs/GaN TF/Sapphire surface under 5 W·cm−2 concentrated light illumination. Ru NPs loaded onto commercial GaN thin films on sapphire substrate is defined as Ru NPs/GaN TF/Sapphire. Source data are provided as a Source Data file.
