Abstract :
In this paper, the silica microspheres having europium ions are fabricated using the powders floating method. The optical characterizations of the silica microspheres having europium ions are performed in the attenuated-total-reflection configuration under excitation of 395 nm laser. When the diameters of the silica microspheres having europium ions are 60 mum and 90 mum, the estimated quality factors of whispering gallery modes are 2100 and 2400 respectively.
