Time evolution of the photoluminescence spectrum of the RNA-functionalized SWCNTs after adding Ni particles. Excitation laser wavelength was 532 nm. The black spectrum was taken right before adding Ni particles, and the red, green, and blue spectra were taken 60, 120, and 180 min, respectively, after adding Ni particles.
