A dramatically different trend was found for

On the contrary, with excitation wavelength of 532 nm (corresponding to the maximum emission of green LEDs), the NdT catalyst showed a very higher reflectance value with respect to complete flower one at 434 nm. In summary, when NdT/OP is excited at 532 nm with green LEDs, OP nanoparticles emit at 434 nm, subsequently, the up-converted visible photons were absorbed by NdT leading to a better efficiency in MB photocatalytic degradation than NdT photocatalyst following a mechanism similar to that one found by Zhang et al. [32].
