Luminescence of hafnium dioxide films produced from hafnium dipivaloylmethanate

Optical Properties of HfO2 Nanoparticles Produced by Laser Ablation

“…4 faint luminescence intensity peaks can be seen at 3.6, 2.3, and 1.6 eV. The luminescence excitation spectrum for each line is weak, which can be explained by the low intensity of the lamp source [16]. The shape of the photoluminescence peaks of the nanoparticles varies with the laser ablation conditions (Fig.…”
