Single crystal Dy3+ doped YNbO4 phosphors were prepared via a high-temperature high-pressure hydrothermal procedure. Under excitation at 270 nm, the Dy3+-doped YNbO4 phosphor shows bright white emission, which is composed of two strong bands at 492 and 576 nm corresponding to the characteristic 4F9/2→6H15/2 and 4F9/2→6H13/2 transitions of Dy3+, respectively. The dominant band was observed...
