- •
CaF2–Bi2O3–P2O5–B2O3 glasses doped with Cr2O3 were crystallized by heat treatment.
- •
Glass ceramic samples were characterized by XRD, SEM, EDS and DTA data.
- •
Optical absorption, FTIR, Raman and EPR studies were carried out on these glass ceramics.
- •
XRD, DTA and SEM studies indicated that the samples contain different crystalline phases.
- •
Studies indicated that part of Cr3 + ions is converted into Cr6 + ions that occupy the Td positions in ceramic matrix.
