Figure 3From: Enhanced photoluminescence of porous silicon nanoparticles coated by bioresorbable polymersFTIR absorption spectra of the samples: uncoated sample before storage in water (solid line), uncoated sample after storage in water (dashed line) and PLGA/PVA-coated sample after storage in water (dotted line). The storage was done in darkness for 2 weeks at room temperature.Back to article page
