Annotation The influence of the substrate temperature on the formation of high-temperature phases of hafnium dioxide in the process of pulsed laser ablation is investigated. It is established that the HfO2 nanoparticles of the high-temperature tetragonal and cubic phases with a quantitative content up to 50 % are formed on the surface of the substrate at room temperature during the laser ablation with intensity of 1010 W/m2. It is shown that with increasing the substrate temperature the average size of the ablated nanoparticles decreases and the quantitative content of the high-temperature phases is increased up to 70 %.
