Size dependent three-photon absorption (3PA) and three-photon-excited photoluminescence (PL) of CdSe/CdS nanorod heterostructures have been investigated using Z-scan and upconversion PL techniques with 150-fs laser pulses at 1300 nm. The PL from these rods show clear cubic power dependence and the 3...
