Novel up‐conversion ( UC ) luminescent nanopowders, Sr 2 CeO 4 : Yb 3+ , Ln 3+ ( Ln = Er , Tm , Ho ) were prepared with Pechini method. The Sr 2 CeO 4 : Yb 3+ , Ln 3+ ( Ln = Er , Tm , Ho ) nanopowders had an orthorhombic crystal structure, and showed olive‐like morphology with the length of about 260 nm and width of about 130 nm. Under 980 nm lazer excitation, the Sr 2 CeO 4 : Yb 3+ / Er 3+ , Sr 2 CeO 4 : Yb 3+ / Tm 3+ , and Sr 2 CeO 4 : Yb 3+ / Ho 3+ nanophosphors exhibit strong green, blue, and green UC luminescence, respectively. The luminescence mechanisms for the doped lanthanide ions were thoroughly analyzed.
