<title>Pulsed laser deposition of boron carbide: spectroscopic study of laser ablation plasma</title>

Micrometric rods grown by nanosecond pulsed laser deposition of boron carbide

“…Studies of the B 4 C laser ablation plumes in the IR and in the UV via optical emission spectroscopy and low-order harmonic generation [16] have revealed the presence of C and B neutral and ion species and of C 2 molecules. The velocity of the gaseous species arriving at the substrate is highly wavelength dependent and is estimated to be 10 times larger at 266 nm than at 1064 nm.…”

“…The in-situ study of the B 4 C laser ablation plasma via optical emission spectroscopy and low-order harmonic generation has been proposed as a guide for controlled thin film synthesis through PLD [16][17][18]. Mostly amorphous B 4 C films have been grown by nanosecond UV laser ablation using the wavelengths of 266 and 248 nm [11,12,15].…”

“…A c c e p t e d M a n u s c r i p t 4 include chemical vapor deposition (CVD) [6,7], laser-assisted CVD [8,9], magnetron sputtering [10] and pulsed laser deposition (PLD) [11][12][13][14][15][16].…”
