Upconversion Luminescence Response of a Single YVO₄:Yb, Er Particle

Micromachines, 2023
We present the results of the luminescence response studies of a single YVO4:Yb, Er particle of 1-µm size. Yttrium vanadate nanoparticles are well-known for their low sensitivity to surface quenchers in water solutions which makes them of special ...
