A series of yttria-stabilized zirconia single-crystals doped with 0.000–0.250 mol% Tb4O7 was prepared by the optical floating-zone method. As shown XRD and Raman spectroscopy, all crystals had a cubic-phase structure. These were initially orange–yellow in color, which is indicative presence Tb4+ ions, but they then became colorless after being annealed H2/Ar atmosphere as result reduction to Tb...

BSA is unfolded by the surfactant CPB and is complexed with Tb (Tb–BSA–CPB). At the excitation wavelength of 290 nm, both BSA and CPB get excited. The CPB emission, which is comparatively blue shifted (310 nm) than that of BSA (340 nm), overlaps with the absorption band of BSA resulting in the energy transfer from CPB to BSA. BSA transfers its energy to Tb, which emits at 490 and 545 nm. When G...

Lanthanide ions have been successfully used as luminescent probes in several biological systems. The terbium (Tb) luminescence is greatly enhanced in Tb(III)-protein systems by non-radiative energy transfer from aromatic chromophores to bound Tb ions. In this study, the luminescent properties of terbium have been used to monitor the metal-peptide interactions of angiotensin II, a linear octopep...

Terbium, a fluorescent probe, which fluoresces primarily with guanine and xanthine bases, has been used to investigate the interaction of platinum complexes with DNA and RNA. c/sDichlorodiammineplatinum(ll), a potent antitumor agent, pro duced a marked enhancement in fluorescence intensity when reacted with double-stranded DNA. This can be explained by the c/s-dichlorodiammineplatinum(ll) produ...

Rare-earth iron garnets (REIG) have recently become the materials platform of choice for spintronic studies on ferrimagnetic insulators. However, thus far studied mainly been REIG with a single rare earth species such as thulium, yttrium, or terbium garnets. In this study, magnetometry, ferromagnetic resonance, and magneto-optical Kerr effect imaging is used to explore continuous variation magn...

We focus on the development of a remote temperature sensing technology, i.e., an optical laser-based sensor, using thermographic phosphors for medical applications, particularly within an electromagnetically hostile magnetic resonance imaging (MRI) environment. A MRI scanner uses a strong magnetic field and radio waves to generate images of the inside of the body. The quality of the image impro...
