We present a study on the temperature response of the plasmon peak of gold nanoparticles (AuNPs) completely encapsulated in soda-lime glass for temperatures ranging from 298 K to 723 K and in ambient pressure air, Ar and aqueous environments. The observed peak position changed with temperature in a linear manner, as expected from the theoretical model also presented in this study. The linear character was upheld in different gaseous environments of inert Ar and ambient air, as well as in both pure deionized water and acidic water. The consistent expected dependence provided proof of the versatility of the encapsulated AuNPs and their robustness to be able to withstand both high temperature and high acidity and still retain their sensing capability. Keywords: Localized surface plasmon resonance, Au nanoparticle, Pure temperature sensing, Fully encapsulation |
