Highly efficient up-conversion luminescence in Er(3+)/Yb(3+) co-doped Na(5)Lu(9)F(32) single crystals by vertical Bridgman method
Er(3+)/Yb(3+) co-doped Na(5)Lu(9)F(32) single crystals with different concentrations of Yb(3+) ions were prepared to investigate their phase structure, up-conversion (UC) properties and mechanism of UC luminescence by Bridgman method. Under 980 nm near-infrared (NIR) excitation, three sharp UC emiss...
