摘要：
Images of cleaved surfaces were obtained for 53ZrF(4)-20BaF(2)-4LaF(3)-3AlF(3)-20NaF (ZBLAN) glasses and fused quartz using an NTMDT atomic force microscope. It is shown that the scatter of particle size depends on the cooling rate and is 21-48.5 angstrom for the cleaved surface of ZBLAN glass obtained by very fast cooling and 68-172 angstrom for the cleaved surface of ZBLAN after slow cooling. For cleaved fused quartz, the range is 25-18 angstrom.
