The hot‐injection synthesis of manganese ion (Mn 2+ )‐doped NaYF 4 :Yb,Er nanocrystals (NCs) with red up‐converting emission and the diameter tunable from 8 to 15 nm is demonstrated. The Mn 2+ dosage, growth temperature, and heating rate determine the doping modes, including surface doping and interior doping. Surface doping produces small NCs and interior doping contributes to the red emission.
