Optical thermometry of MoS2:Eu3+ 2D luminescent nanosheets

Here, we report the incorporation of Eu3+ ions into a MoS2 2D material through a two-step bottom-up hydrothermal approach. Temperature dependent measurements in the 60-360 K range were carried out to determine the optical thermometric properties of the material. This material could offer a new strategy to exploit temperature sensors and heaters.
