a FT-IR spectra of solid EA, E–G, E–G–P0.5, and GEL. b DSC curves and c PXRD patterns of EA, E–G, E–G–P0.5 glasses. d SAXS curves of glassy EA and E–G. e SEM images of cross-section (upper, scale bar: 3.7 μm) and plane (below, scale bar: 0.5 μm) for E–G glass. f UV-Vis-NIR transmittance spectra of E–G and E–G–P0.5 glasses. Two bands at approximately 1730 nm and 1500 nm, and one band at 348 nm originate from water and PCA absorption in PCA-doped glass, respectively.
