Nd^(3+)-doped tel.urite gl.sses are promising material. for thermometers based on the fl.orescence intensity ratio(FIR)***,at high Nd^(3+)concentrations,energy transfer(ET)processes such as optical.reabsorption and cross-rel.xation can affect the Nd^(3+)emission,which has been l.ttl. expl.red in the ***,the present work investigated the use of Nd^(3+)-doped tel.urite gl.ss(sampl.s doped with Nd^(3+)at 0.2 mol.,0.5 mol.,2.0 mol.,and 4.0 mol.)in fl.orescence thermometers,in the temperature range from 299 to 371 *** resul.s indicate a strong dependence of the FIR parameters on the Nd^(3+)concentration,due to changes in the emission band profil.s caused by optical.reabsorption of the Nd^(3+)emissions and cross-rel.xation processes.A decrease of the rel.tive sensitivity of the ratio^(4)F_(5/2)→^(4)I_(9/2)/^(4)F_(3/2)→^(4)I_(9/2)is observed for sampl.s doped with higher amounts of Nd^(3+).The maximum rel.tive sensitivity at 299 K is 3.00%/K,which is the highest val.e among the reported Nd^(3+)ions.
