ions were observed

respectively. The green emission around 520 nm and the red emission around 660 nm continuously increase with increasing of temperature. The emission around 545 nm increases from 84 to 204 K and then decreases from 204 to 483 K. The temperature dependen ce of intensity characteristics was systematically analyzed by a simple three-level system.
