- •
XRD study shows orthorhombic structure which goes well with the perovskite structure.
- •
The FTIR study is correlated with bending and stretching of Y
O, AlO, BO, OH bonds.- •
UV and gamma irradiated YAlO3:Dy3+ doped phosphors shows three or four peaks indicating more than four traps were present.
- •
TL emission spectrum is characteristic of the host lattice.
