Formation of High Mass C_nclusters (n > 100) by Laser Ablation/Desorption Coupled with Mass Spectrometry

IR and UV/VIS Spectroscopic Characterization of the Higher Fullerene C76-D2 for Its Quantitative and Qualitative Determination

“…It should be expected also that the higher fullerenes can be found and quantified in space because of their exceptional stability toward high temperatures and cosmic rays [1][2][3][30][31][32][33][34], as well as the possibilities of their formation through coalescence of smaller fullerenes by laser ablation of carbon and dehydrogenation of hydrogenated fullerenes, fulleranes [1][2][3][30][31][32][33][34][35][36][37].…”

L'ablation/ionisation laser appliquée à la préparation et à l'étude des fullerènes

“…Ainsi, le comportement de fullerènes purs (Cgo, C70, C76, C84) sous l'influence d'irradiations laser UV (223 et 266 nm) et visible (566 nm) à différentes densités de puissance conduit aux constatations suivantes [14]. Quel que soit le fullerène étudié, les spectres de masse montrent une distribution d'agrégats carbonés de hautes masses (n>100) lorsque l'irradiance est supérieure au seuil de désorption des fullerènes (>10 6 W/cm 2 ).…”

Determination of New IR and UV/VIS Spectroscopic Parameters of the C84-D2:22 Isomer for Its Quantitative Assessment, Identification and Possible Applications

“…It can be assumed that the higher fullerenes also exist in space, due to their extraordinary thermodynamic stability, persistence toward high energy γ radiation [19][20][21][22][23][42][43][44][45][46][47][48][49][50] and corpuscular collisions. Their formation is possible through the coalescence of smaller carbon clusters [22,23], as well as by decomposition of some derivatives, such as dehydrogenation of hydrogenated fullerenes, fulleranes [19][20][21][22][23][24][25][26][27][46][47][48][49][50][51][52][53].…”
