Self-trapped exciton luminescence of tellurium doped zero-dimensional tetraethyl tin chloride for optical thermometry

Te 4+ doped (TEA) 2 SnCl 6 MCs were synthisized by solvothernal method for the first time, of which structure was obtained by crystal/DFT. Maximium absolute/relative temperature sensitivities reach 0.57% K −1 and 1 × 10 −2 K −1 for optical thermometry.
