ABSTRACT:
In this paper various samples with varying concentration of Ho3+ s (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 mol %) and constant concentration of Er3+ (1.5 mol %) ions were studies for its structural and photoluminescence (PL) properties. The prepared samples underwent the PL studies and an IR source of 980 nm was used to excite the samples. It exhibited 05 peaks centered at 409 nm, 455 nm, 491 nm, 524 nm and 657 nm. Out of these 05 peaks 02 peaks centered at 524 nm and 657 nm were prominent and are attributed to 5F3  5I8 and 5F5  5I8 respectively. The sample with 2.5 mol% of Ho3+ provided the highest intensity of PL. Scanning Electron Microscope Images of the sample with optimum PL was taken for resolutions of 5k, 10k, 20k and 60k. The images suggested that the particles are spherical and agglomerated.
