Here, we selected nitride La3Si6N11 (LSN) as host material to achieve Yb3\u00fe<br>NIR emission upon low-energy charge transfer (CT) excitation. The obtained phosphor LSN:Yb3\u00fe has a<br>broad CT excitation band ranging from 250 to 500 nm and narrowband NIR emissions ranging from 950<br>to 1100 nm centered at 983 nm. On the basis of spectral data, the vacuum referred binding energies<br>(VRBE) schemes are constructed to locate energy levels of all lanthanide ions in LSN.
