| Abstract | The luminescence properties of green Ba4Si6O16:Eu2+, rare-earths (RE) (RE = Sc, Y, La and Lu except Pm) phosphors are reported. Their long-lasting phosphorescence is discussed in view trap depths concentrations determined from thermally stimulated experiments. A second emission band centered at 439 nm was evidenced low temperatures, which stems the substitution Eu2+ two non-equivalent Ba2+ sites Ba4Si6O16. mechanoluminescence RE described, a new mechanism proposed, case where Ho3+, involving distribution 0.694 to 0.924 eV. Mechanical loading (post UV irradiation) induces decrease depth distribution, leading an increase intensity, whereas drop intensity observed upon unloading, following faster release charge carriers. |
