The thermal dependence of the luminescent properties of Eu3+ doped Y2MoO6 phosphor and its potential application in temperature sensing

The temperature dependence of luminescence performance is crucial for most applications of the luminescent materials. Temperature dependent emission spectra of Y2MoO6: 20% Eu3+ phosphor were investigated over a very large temperature range from 20 to 500 K, and the experimental result shows that the emission intensity decreases dramatically with the temperature increasing. With the help of the decay curves of the emission, the possible mechanisms for the thermal quenching behavior of the Eu3+ luminescence were discussed. Considering the acute change of the emission intensity with temperature, Eu3+ doped Y2MoO6 could be a promising candidate for temperature sensors.
