Lanthanide grafted phenanthroline-polymer for physiological temperature range sensing [PDF]

, 2019
Accurate measurement of the temperature is crucial as it determines the dynamics of almost any system. Conventional contact thermometers are not well suited for small scale measurements. Temperature dependent luminescent materials, i.e.

Structure, photoluminescence, Judd–Ofelt analysis, and thermal stability studies of Ho3+/Yb3+ Co-doped YNbO4 green phosphors

AIP Advances, 2023
A series of YNbO4:Ho3+/Yb3+ phosphors with varying concentrations of Yb3+ were synthesized using a high-temperature solid-state method. To ascertain the presence, structure, and purity of YNbO4:Ho3+/Yb3+, the crystal structure of the luminescent powder ...

Luminescence measurement of Feldspar

, 2022
Abstract In their ideal form, feldspars are wide bandgap (> 5 eV) insulators with a well-defined crystal structure. A natural sample may contain different feldspar phases, disorders, twinning effects, fractures, dislocations, and highly variable impurity contents.

Sensitivity of Ru(bpy)_2dppz^(2+) Luminescence to DNA Defects [PDF]

, 2009
The luminescent characteristics of Ru(bpy)_2dppz^(2+) (dppz = dipyrido[3,2-a:2′,3′-c]phenazine), a DNA light switch, were investigated in the presence of oligonucleotides containing single base mismatches or an abasic site.
