摘要: The growth and the dynamics of a tungsten nanoparticle cloud were investigated in direct-current low pressure argon glow discharge. Real-time analyses dust particle size number concentration performed in-situ by light extinction spectrometry, while spatial was with laser light-sheet scattering method. Additional off-line electron microscopy Raman spectroscopy measurements also for comparison purpose. This experimental work reveals existence an agglomeration phase followed appearance new generation. While growing, is pushed towards anode discharge edge. Afterwards, generation can grow space freed first nanoparticles. continuous growth, below spectrometry scanning positions, explains apparent dissimilarities observed between in-line optical analyses.
