Advanced Materials for Fiber Communication Systemsomposition which has the minimum value of Landau-Placzek ratio (R.). Er. doped fluoroaluminate glasses were prepared by the same technique. The near infrared luminescence spectra of glasses corresponding to the .I. → .I. transition of Er. ions were observed. The mechanism of upconversion emissions E
