In this work, CePO4:Ho3+ nanomaterials are prepared by a productive polyol method which shows the dual mode of behavior in Photoluminescence. The up-conversion spectra at 980 nm excitation display a sharp brilliant peak at ∼520nm - ∼550nm, ∼630 nm, - 670 nm resulting in the (5F4,5S2→5I8) and (5F5→5I8) of Ho3+ ions, and it is also found that the sample radiates green and red colors. The down-conversion peaks show maximum absorption at 300nm which exhibit peaks at ∼450nm, ∼520nm- ∼550 nm, ∼and 630 nm -∼670 nm respectively. the rare earth ions doped nanomaterials show up-conversion radiation and down-conversion radiation. This type of energetic work has an extensive range of applications, including lasers, metal ion sensors, bio-imaging, temperature and stress sensors, radiation damage sensors, and defense and cyber security.
