Spectral Analysis of Ca_2-XBO₃Cl:xDy³⁺ Phosphors

Abstract:

PL spectra of Ca2-xBO3Cl:xDy3+ phosphors excited by 390 nm n-UV light. The intensity of both blue and yellow emissions starts to increases with the growing contents of Dy3+ ions, the strongest intensity of Dy3+ emission courses in the Ca1.95BO3Cl:0.05Dy3+ phosphor, subsequently it decreases with further adding Dy3+ ions due to concentration quenching. it can be concluded that the environment of Dy3+ ions may be less influenced due to the clustering of Dy3+ ions in the investigated phosphors after concentration quenching.
