a Schematic diagram of the experimental setup for the measurements. The arrows represent the laser beam directions for the Raman scattering and heating measurements. b Optical micrographs of the sample chambers containing NH3BH3 (AB) and Pt electrodes in the representative cells (Cell-6 and Cell-7) before and after laser heating. The edges of Y-Ce film are marked with the red lines, and the blue arrows in the right photos indicate the parts with apparent changes after heating. c Raman spectra for the synthesized Y0.5Ce0.5 hydrides collected at the apparent-changing parts (blue arrows in the right Fig. 1b) in the sample chamber. The Raman bands of the diamond and H2 after laser heating are presented. The low-frequency Raman spectra are scaled for the clarity.
