Luminescence properties of KAlP₂O₇ crystals doped with chromium ions

Luminescence properties of KAlP₂O₇ crystals doped with chromium ions

Luminescence properties of the KAlP₂O₇ crystals doped with the chromium ions were investigated. Luminescence spectra consist of two main bands: one of them lies in the blue-green spectral region and the other lies in the red spectral region. The maximum positions of the bands depend on the crystal c...
