Temperature-Dependent Luminescence of Red-Emitting Ba<sub>2</sub>Y<sub>5</sub>B<sub>5</sub>O<sub>17</sub>: Eu<sup>3+</sup> Phosphors with Efficiencies Close to Unity for Near-UV LEDs

Temperature-Dependent Luminescence of Red-Emitting Ba<sub>2</sub>Y<sub>5</sub>B<sub>5</sub>O<sub>17</sub>: Eu<sup>3+</sup> Phosphors with Efficiencies Close to Unity for Near-UV LEDs

Solid state white light sources based on a near-UV LED chip are gaining more and more attention. This is due to the increasing efficiency of near-UV-emitting LED chips and wider phosphors selection if compared to devices based on blue LED chips. Here, a brief overview is given of the concepts of gen...
