Flashing Carbon on Cold Surfaces

摘要: The formation of carbon particles on cold surfaces takes place when rare-gas solids containing trapped vapor molecules are sublimed. This process is accompanied by violent effects such as flashes lightemission and splashing luminous fragments, both observable with the naked eye. recorded optical emission spectrum shows a continuum attributable to blackbody radiation ∼2500 K. We believe associated exothermic reactions following rearrangement bonds, which leads from metastable sp-carbon chains more stable sp 2 form particles.
