Tunable luminescence of Bi(3+)-doped YP(x)V(1-x)O4 (0 ≤ x ≤1).

A systematic investigation of the luminescence spectroscopy of Y(P,V)O4:Bi(3+) is presented. The emission spectra and the decay curves are measured as a function of the host morphology, composition, temperature, excitation wavelength, and doping concentration. On this basis, the nature of the excited states and the radiative and non-radiative relaxation… CONTINUE READING
