Investigating the impact of molybdenum content on the room-temperature optical properties of Li₂WO₄ crystals grown by low-thermal-gradient Czochralski technique.

and rotation rate of 5 rpm. The crystal structure was investigated using powder X-ray diffraction, which confirmed the single-phase nature and trigonal structure (space group R3) for all compositions. Differential scanning calorimetry did not reveal phase transitions in the temperature range 303-1153 K. The influence of partial substitution of W with Mo on the luminescence properties is demonstrated and a correlation between Mo concentration and emission characteristics is established.
