摘　　要：Lanthanide(Ln^(3+))-doped photon avalanche(PA)upconversion nanoparticles(UCNPs)have great prospects in many frontier applications,such as super-resolution bioimaging,miniaturized lasers,single-molecule tracking,and quantum optics.However,it remains challenging to realize PA in colloidal Ln^(3+)-doped UCNPs at room temperature(RT),due to the deleterious quenching effect associated with the surface and lattice OH^(-)defects.
