▎ 摘　　要

The suppression of the opal crystal luminescence under infiltration of graphene oxide nanoparticles (GONP) into interglobular cavities of a photonic crystal (PC@GONP) was found. Additionally a 3-fold decrease of the Raman signal from the graphene oxide and a 10-fold increase of the PC@GONP absorbance were simultaneously found leading to an improved contrast of the PC and a 21 nm red shift of the optical transmittance minimum in the PC stop zone region. The comparison of the surface mapping of PC@GONP with GONP deposited on a Si/SiO2 (Si/SiO2@GONP) surface was done using D and G graphene Raman bands. Raman spectra details allowed to find noticeable changes in the D-to-G modes intensity ratio and their peak positions for both GONP-based samples suggesting their significant spectroscopic and structural heterogeneity. A small number of structural defects was observed in the PC@GONP that improve optical and crystalline properties of GONP. A Clear observation of the Raman active opal and GONP modes simultaneously with the appearance of the second order Raman bands within 2000-3500 cm(-1) range that are absent in the Raman spectra of the pristine GONP suggests the formation of new bonds of graphene at the interface, a structural modification of the graphene oxide in the PC nanocavities, and a modification of Raman selection rules.
