Figure 4From: Prolate spheroidal hematite particles equatorially belt with drug-carrying layered double hydroxide disks: Ring Nebula-like nanocomposites Effect of LDH coating on the optical properties of hematite core. Diffuse reflectance UV/Vis spectra of uncoated hematite (A), NO3-LDH-coated hematite (LDH peak at 218 nm) (B), and SAL-LDH-coated hematite (LDH and SAL peaks at 224, 240, and 319 nm) (C).Back to article page
