Аннотация: Multimetallic neodymium-ytterbium-gadolinium compounds with 9-anthracenate and 9-acridinate anion were tested in order to create the first luminescence thermometer for elevated temperatures. High luminescence intensity and high signal resolution were reached thanks to the concentration quenching elimination due to the partial substitution of the emitting ions with Gd3+. As a result, NIR emitting materials for the luminescent thermometry in the wide temperature range (83-393 K) based on lanthanide coordination compound (CCs) were obtained. The best thermometric properties among the studied systems was demonstrated by Yb0.02Nd0.12Gd0.86(ant)3: its temperature sensitivity reached 1.8%К-1 in temperature range of 293-393 K.
