Abstract
The Mn2+-doped optical quality Li2–2xMg2+x(MoO4)3 single crystals were grown by the low-thermal-gradient Czochralski method. Photoluminescence (PL) and photoluminescence excitation (PLE) spectra for investigated crystals were studied at 77 K and 300 K. Green and red emission bands of Mn2+ are interpreted in terms of different structural positions that occupied by impurity manganese ions in Li2–2xMg2+x(MoO4)3. Absorption investigations show the characteristic Mn2+ absorption features, namely a sharp absorption peak at 410 nm. CIE investigation results show that Mn2+-doped Li2–2xMg2+x(MoO4)3 single crystals are prospective materials in pcWLED due to from green to red emission bands in PL spectrum. Correlated color temperatures (CCT) and color purity (CP) of investigated crystals were calculated.
