Synthesis and characterizations of CsI(Na) and CsI(Na)@MgO nanoparticles. a Schematic illustration of CsI(Na)@MgO synthesis and surface modification. b SEM of CsI(Na) nanoparticles. Scale bar, 100 nm. The average nanoparticle size was 55 ± 15 nm, determined by ImageJ. c XRD spectra of CsI(Na)@MgO, CsI(Na), and CsI (no Na dopant) nanoparticles, as well as a CsI standard (PDF#06-0311 from the JCPDS database). d TEM image of a single CsI(Na)@MgO nanoparticle. e EDX elemental analysis of a single CsI(Na)@MgO nanoparticle. Scale bar, 100 nm. f X-ray luminescence spectra of CsI(Na) (dashed red) and CsI(Na)@MgO (solid red) nanoparticles, along with the absorption spectrum of PpIX (blue).
