哈佛大学、德国马尔堡大学和荷兰特文特大学的研究人员已首次阐述单气泡声致发光(SBSL)的光发射,这是一种水中声驱动气泡周期性破坏并产生紫外光闪射的现象,单气泡声致发光是由于在20000K~30000K温度下等离子体的短暂形成。气泡中的多数气体都被驱动到溶液中,只留下氩和?.. Researchers at Harvard University, the University of Marburg in Germany and the University of Twente in the Netherlands have described for the first time the light emission of single-bubble sonicated luminescence (SBSL), a phenomenon in which sound-driven bubbles in water periodically destroy and produce ultraviolet light, The single bubble sonoluminescence is due to the brief formation of the plasma at a temperature of 20000K to 30000K. Most of the gas in the bubble is driven into solution, leaving only argon and?
