Plasma treatment is a versatile technique for surface treatment at a relatively low temperature. Silicon dioxide microparticles (average size about 1 micrometer) have been treated in an argon plasma using an inductive coupled plasma (ICP) reactor. The modified SiO2 powder was pressed into pellets and characterized by optical absorptance and photoluminescence spectroscopy. Argon bombardment at low pressure increased optical absorption of SiO2 powder as well as blue photoluminescence indicating an increase in defect states on the surface of the microparticles.
