S.1. SERS mapping of two bands of the CV dye for w-glass@AgNP and t-glass@AgNP in two exciting radiations (532 and 785 nm)

Figures S1 and S2 present the SERRS mappings at λ0= 532 nm of the band at

910 cm-1 of CV for APTMS deposited from water and toluene, respectively. Figures S3

and S4 present the SERRS mappings at λ0= 532 nm of the band at 1180 cm-1 of CV for

APTMS deposited from water and toluene, respectively Figures S5 and S6 present the

SERS mappings at λ0= 785 nm for the band at 910 cm-1 of CV for APTMS deposited

from water and toluene, respectively. Figures S7 and S8 present the SERS mappings at

λ0= 785 nm for the band at 1180 cm-1 of CV for APTMS deposited from water and

toluene, respectively.
