“…3 is the digital image of NLZ6 sample under excitation of 0.25 mW 808 nm laser, and the green upconversion emission is strong to be seen by naked eyes. The red emission may be attributed to 4 states. However, the green emissions reach the "saturation" state when the concentration of codoped rare earth ions is larger than a certain threshold.…”

“…After one-photon ET process: 2 F 5/2 (Yb 3+ ) + 4 I 15/2 (Er 3+ )→ 2 F 7/2 (Yb 3+ ) + 4 I 11/2 (Er 3+ ), 4 I 11/2 (Er 3+ ) + 4 I 11/2 (Er 3+ )→ 4 F 7/2 (Er 3+ ) + 4 I 15/2 (Er 3+ ). The CR process between the two neighboring Er 3+ ions is responsible for the population of the 4 S 3/2 / 4 H 11/2 states.…”

“…However, there is a heavy limitation for the application of powder NaYF4 in optical amplifiers and solid-state laser. Hence, NaYF4 transparent glass ceramic is considered as a good candidate for practical application due to its good spectroscopic properties, chemical and mechanical stability [4][5][6][7].…”
