Gd3+ doped CuInS2/ZnS nanocrystals with high quantum yield for bimodal fluorescence/magnetic resonance imaging

(a) Linear relationship between T1−1 and Gd3+ concentrations, (b) T1-weighted MRI (top) and corresponding pseudo-color images (bottom) of GCISZ NCs with different Gd3+ concentrations (The value of T1−1 was collected basing on readings from (b))
