Structural and Spectroscopic Effects of Li+ Substitution for Na+ in LixNa1-xCaGd0.5Ho0.05Yb0.45(MoO4)3 Scheelite-Type Upconversion Phosphors

“…These lanthanide-activated double molybdates provide stable chemical and physical characteristics with excellent optical properties for favorable lanthanide admittance, relatively low phonon energy, and versatile applications in such fields as solar cells, lasers, biomedical and optoelectronic devices, optical sensors, etc. [ 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. Many molybdate crystals are appropriate for the incorporation of rare earth (Ln) ions in their structure, and the materials are considered as potential hosts for the creation of phosphors to be used in photonic structures [ 2 , 3 , 4 , 7 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ].…”

Multiple fluorescence-temperature feedback in Y7O6F9:Er/Yb crystal-embedded polyacrylonitrile fibers

“…Some works have been reported on the temperature-dependent up-conversion luminescence of rareearth ions. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] Among various temperature-dependent fluorescence parameters, the temperature-based fluorescence intensity ratio (FIR) can circumvent the disturbances of the local environment and provide real-time feedback results. [41][42][43][44][45][46][47][48][49][50] In addition, Nd 3+ -based thermometers were proposed for bio-applications, and new multipurpose strategies, Cr 3+ -based Boltzmann thermometers, were demonstrated to be particularly promising.…”
