Abstract
Upconversion YVO4-based nanoparticles doped with Yb and Er are synthesized via thermal decomposition in an atmosphere of argon. These nanoparticles display strong luminescence in the range of 510–560 nm. The temperature dependence of the intensity of luminescence at 541 nm is much stronger than that at 530 nm. The strong temperature dependence of the intensity of luminescence at 541 nm offers the possibility of designing a nanoscale temperature sensor in the range of 285–325 K.
