Optothermal effect

WebFeb 2, 2024 · The optothermoelectric phenomenon involves two characteristic energy-conversion processes (i.e., light to heat and heat to electric potential), which are known as the optothermal effect and the thermoelectric effect, respectively. WebJul 4, 2024 · Optothermal Effect In daily life, air bubbles occur in cold water during heating because the solubility of air decreases when the temperature increases, and gases originally dissolved in the water are released. This principle can also be used to generate bubbles at the micro/nanoscale levels.
