From: Crystal growth and optical characteristics of beryllium-free polyphosphate, KLa(PO3)4, a possible deep-ultraviolet nonlinear optical crystal

Figure 1

The photographs and their morphological schemes of as-grown KLa(PO3)4 crystals by different cooling rates: (a) 1 °C/1.5 days, (b) 1 °C/2 days and (c) 1 °C/3 days.

Their mass and sizes are 18.47 g and 40 × 35 × 8 mm3 for (a), 4.01 g and 19 × 21 × 7 mm3 for (b) and 0.73 g and 10 × 16 × 3 mm3 for (c), respectively.
