Figure 6.

Three-dimensional plot showing the dependence on laser heating for the Raman spectra of Cs2RuO4 heated with 514 nm (Ar+) laser. The x-axis represents the wavenumbers, y-axis shows the laser power measured at the sample surface, and z-axis (change of colors) represents the variation of Raman intensity. Intensity increases from blue to red. Arrows indicate appearance of Raman modes above 36 mW (shown with dashed line).
