Stable Efficient Solid-State White-Light-Emitting Phosphor with a High Scotopic/Photopic Ratio Fabricated from Fused CdSe-Silica Nanocomposites

Stable, bright‐white‐light‐emitting phosphor is fabricated from 5.5‐nm CdSe quantum dots that are incorporated into a silica gel and calcined at 500 °C under air. Excited by UV radiation, the emitted light has almost pure white‐light coordinates of (0.34, 0.36) on the CIE (Commission internationale...

Summary:Stable, bright‐white‐light‐emitting phosphor is fabricated from 5.5‐nm CdSe quantum dots that are incorporated into a silica gel and calcined at 500 °C under air. Excited by UV radiation, the emitted light has almost pure white‐light coordinates of (0.34, 0.36) on the CIE (Commission internationale de l’éclairage) chromaticity chart and a Scotopic/Photopic ratio of 2.56.
