Abstract


Europium (Eu) doped Calcium borophosphate (CBP) phosphors were synthesized via solid-state diffusion method. The prepared Europium (Eu) doped Calcium borophosphate (CBP) powder was heated up to 600 ℃ for 6 h for a complete diffusion of ions in the powder system. XRD results showed that the prepared phosphors exhibit a well-crystallized hexagonal phase. The complete diffusion inside the CBP/Eu powder system has been confirmed by the presence of elements such as P, O, Bi, Ca, C, Eu, and B. Apart from that, the synthesized powder system has shown a down-conversion property where the Eu3+ activated ion was excited at 251 nm. Under the excitation of 251 nm, CBP/Eu phosphor showed intense emissions peaking at 591,617, and 693 nm due to the 5D0 → 7F1, 5D0 → 7F2, and 5D0 → 7F4 transition of Eu3+ ions. The obtained results suggest that the CBP/Eu phosphors have the potential for spectral response coating materials to improve the photovoltaic (PV) panel efficiency.
