“…The resistivity value of the films is in the range between 4.1 and 802.1 X cm at room temperature. The decrease in resistivity with increasing film thickness can be attributed to the improvement of the crystallization and in morphological changes of the films [28,34]. As can be seen in Fig.…”

“…The red-emitting phosphors doped with trivalent rare-earth (RE) ions have been widely used in the development of emissive display and tricolor lamp industry for two decades. In the past, Li + ion has been introduced in to different oxide hosts such as Y 2 O 3 :Eu 3+ [2], Gd 2 O 3 :Eu 3+ [3], SnO 2 :Eu 3+ [4], acting as a co-activator and charge compensator. It has been found that the PL intensity was substantially enhanced after Li + doping.…”

a b s t r a c tGd 2 O 3 :Eu 3+ (4 mol%) nanophosphor co-doped with Li + ions have been synthesized by low-temperature solution combustion technique in a short time. Powder X-ray diffractometer (PXRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), UV-VIS and photoluminescence (PL) techniques have been employed to characterize the synthesized nanoparticles. It is found that the lattice of Gd 2 O 3 :Eu 3+ phosphor transforms from monoclinic to cubic as the Li + -ions are doped. Upon 254 nm excitation, the phosphor showed characteristic luminescence 5 D 0 → 7 F J (J = 0-4) of the Eu 3+ ions. The electronic transition located at 626 nm ( 5 D 0 → 7 F 2 ) of Eu 3+ ions was stronger than the magnetic dipole transition located at 595 nm ( 5 D 0 → 7 F 1 ). Furthermore, the effects of the Li + co-doping as well as calcinations temperature on the PL properties have been studied. The results show that incorporation of Li + ions in Gd 2 O 3 :Eu 3+ lattice could induce a remarkable improvement of their PL intensity. The emission intensity was observed to be enhanced four times than that of with out Li + -doped Gd 2 O 3 :Eu 3+ .

“…But the studies on the near-infrared absorption of Sb-and Pd-doped assemblies are very rare. As we know, the electrical, optical and magnetic properties of nanomaterials can be modified by doping [13,[14][15][16][17][18][19]. For example, to modulate the optical properties, different rare earth elements were used as dopant in materials [20][21][22][23].…”
