Figure 5

(a) Temperature distribution on the surface of conventional LED chip. (b) Temperature distribution on the surface of rGO-embedded chip. The images are obtained under 100 mA current injections. The scale bar located at the right of b gives an estimation of the temperature associated with different colours.
