“…Importantly, the 4 relative emission intensity of the bands centered around 520 nm and 540 nm is temperature dependent due to the change in the electronic population of the thermally-coupled excited states with temperature (see Supporting Information for details). 8,17,18 For our study, only the highlighted bands in Figures 1(c) and 1(d) were used in order to reduce the experimental error in the determination of the thermal changes (see Supporting Information for details).…”

“…In this type of measurement, the optical emission is used to determine the temperature from an emitting object whose size is smaller than the diffraction limit . Based on this principle, we have used Er 2 O 3 nanoparticles emitters as local temperature probes . This method uses erbium oxide nanoparticles to measure the absolute local temperature around the nanoparticle with a resolution that is limited by the size of the nanoparticle or nanoparticle cluster (50–450 nm).…”

An optical nanothermometer technique based on laser trapping, moving and targeted attaching an erbium oxide nanoparticle cluster is developed to measure the local temperature. The authors apply this new nanoscale temperature measuring technique (limited by the size of the nanoparticles) to measure the temperature of vapor nucleation in water. Vapor nucleation is observed after superheating water above the boiling point for degassed and nondegassed water. The average nucleation temperature for water without gas is 560 K but this temperature is lowered by 100 K when gas is introduced into the water. The authors are able to measure the temperature inside the bubble during bubble formation and find that the temperature inside the bubble spikes to over 1000 K because the heat source (optically-heated nanorods) is no longer connected to liquid water and heat dissipation is greatly reduced.

“…Here, we illustrate two recent thermal imaging results in Figure 3c,d. Figure 3c shows the experimental results of Baral et al [100] obtained through a scanning optical probe thermometry technique based on measuring the photoluminescence of a laser-trapped erbium oxide nanoparticle to obtain the absolute temperature of optically excited Au nanodots with a spatial resolution limited by the size of the trapped nanoparticle. In particular, Figure 3c(ii) shows the measured temperature profile has a Gaussian shape, which can be interpreted as the convolution of the point spread function of the scanning probe and the theoretical temperature profile (e.g., Figure 3b).…”

more than a 100 years to the beginning of the twentieth century. [1] However, owing to the recent improvements in nanofabrication and characterization techniques, it was only in the last decades that plasmonics emerged as a prolific area of applied optics. Phononics is the field of condensed matter physics that studies collective vibrational modes of matter (phonons) as means to carry energy (heat) and information (vibration and sound). Beginning with atomic scale models describing the lattice dynamics, its theoretical roots go back to the foundations of the field of condensed matter physics itself before the first half of the twentieth century [2,3]. Analogously to plasmonics, the ability to fabricate structures with subm µ features is now opening possibilities for exploiting phonon propagation hence promoting a renewed interest in the phononic field. Even more importantly, the nowadays advanced micro-and nano-fabrication technology enables the actual realization of opto-thermo-mechanical nanodevices [4,5] where the interaction between photons, electrons, and phonons can be properly investigated and exploited. Starting from the seminal work of Ritchie in 1957, [6] numerous studies have been performed on systems supporting plasmonic effects, such as metallic slits or perforated metallic films together with hybrid structures formed by metal and dielectric. [7] Plasmonic nanostructures have especially attracted a lot of attention for their ability to couple with light whose Plasmonic nanostructures have attracted considerable attention for their ability to couple with light and provide strong electromagnetic energy confinement at subwavelength dimensions. The absorbed portion of the captured electromagnetic energy can lead to significant heating of both the nanostructure and its surroundings, resulting in a rich set of nanoscale thermal processes that defines the subfield of thermoplasmonics with applications ranging from nanochemistry and nanobiology to optoelectronics. Recently, phononic nanostructures have started to attract attention as a platform for manipulation of phonons, enabling control over heat propagation and/or mechanical vibrations. The complex interaction phenomena between photons, electrons, and phonons require appropriate modelling strategies to design nanodevices that simultaneously explore and exploit the optical, thermal, and mechanical degrees of freedom. Examples of such devices are micro-and nanoscale opto-thermomechanical systems for sensing, imaging, energy conversion, and harvesting applications. Here, an overview of the fundamental theory and concepts crucial to the modelling of plasmo-phonon devices is provided. Particular attention is given to micro-and nanoscale modelling frameworks, highlighting their validity ranges and the experimental works that contributed to their validation and led to compelling applications. Finally, an open-ended outlook focused on emerging applications at the intersection between plasmonics and phononics is presented.
