Paper Abstract

We report the substrate effects on the zero-phonon transitions and suppression of phonon side bands in the NV center spectrum. Fluorescence spectra of NV centers in cryogenic temperatures were measured by depositing diamond nanocrystals on different substrates including glass slides, undoped Si, and silica (1~2μm) on undoped Si (SiO2/Si). We found that SiO2/Si substrate was an effective substrate to suppress the phonon side band from spectra of NV- centers. Temperature dependence of NV- zero-phonon line Debye-Waller factor on Si and SiO2/Si were measured, from 2.5K to 230K, Debye-Waller factor decreased linearly on both of the two substrates.
