Bottom Line: The comparison between SiO2 and SiNx host matrices in the optical properties of the multilayers is detailed.The effect of specific annealing treatments on the optical properties is studied and we report a higher visible luminescence with a control over the thermal budget when SiO2 is replaced by the SiNx matrix.The latter seems to be a potential candidate to replace the most sought SiO2 host matrix.

ABSTRACT
In this article, we have fabricated and studied a new multilayer structure Si-SiO2/SiNx by reactive magnetron sputtering. The comparison between SiO2 and SiNx host matrices in the optical properties of the multilayers is detailed. Structural analysis was made on the multilayer structures using Fourier transform infrared spectroscopy. The effect of specific annealing treatments on the optical properties is studied and we report a higher visible luminescence with a control over the thermal budget when SiO2 is replaced by the SiNx matrix. The latter seems to be a potential candidate to replace the most sought SiO2 host matrix.

Figure 1: FTIR spectra of the multilayer structures at Brewster's angle.

Mentions: Figure 1 shows the FTIR spectra obtained for the non-annealed SRSO/SiO2, SiNx/SiO2, and SRSO/SiNx multilayers. The spectra were recorded at the Brewster angle of 65° that enables the detection of the LO3 mode of silica at about 1250 cm-1 in addition to the TO3 mode located near 1080 cm-1.
