One-step growth of lanthanoid metal–organic framework (MOF) films under solvothermal conditions for temperature sensing†
Abstract
A one-step direct solvothermal synthesis of an Ln metal–organic framework (MOF) film is reported. The LnHL (Ln = Tb and Gd) films that were deposited on a Gd2O3 subtrate are continuous and smooth. The Gd0.9Tb0.1HL film can be used as a ratiometric thermometer, showing good linear behaviour in the temperature range of 110–250 K with a sensitivity up to 0.8% K−1.
