Red And Green Luminescence Properties Of Eu3+ And Tb3+:Zrf4-Znf2-Alf3-Baf2-Yf3 Glasses

Fluoride glasses are reported to possess low phonon vibrational energies with extended infrared transmittance. They have low nonlinear refractive indices because of the small size of the F- ion in association with its strongly ionic bonding character. These are good hosts for accommodating the required amount of rare earth active ions needed for the development of an important class of materials with numerous practical applications such as in planar waveguides. This paper reports on the development and photoluminescence analysis of Eu3+ or Tb3+ containing 20ZrF4.3OZnF2.25AlF3.10BaF2.14YF3 glasses.
