Laser-Heated Gas-Phase Condensation

We use a laser-heated method to vaporize material to form gas-phase clusters. By adjusting the atmosphere in the chamber in which we do this, we can control the size of the particles that ultimately form. Figure 1 shows a schematic of the vaporization chamber.

• Nanocrystal synthesis chamber.
• ZrO₂ nanocrystals.

The cover of Materials Letters in 1995 shows a micrograph of ZrO₂ nanoparticles of approximately 1-2 nm diameter (the bar is 20 nm). Read all about it in
