a) Scheme of LSR synthesis and fabrication of glass micro‐optics. The LSR sol can be considered as soft, flexible, and nanometer‐sized particles. b) The 29Si NMR spectra of LSRs. c) The1H NMR spectra of LSRs. d) The FTIR spectra of LSRs. After normalizing all curves based on Si‐O peak (1066 cm–1), the ratio of integrations of C═O (1723 cm–1) peaks from LSR6.5 to LSR10, to LSR15, to LSR20 is 1:1.5:2.3:3.0.
