Optical properties of europium-doped Gd2O3 waveguiding thin films prepared by the sol–gel method

Preparation of Y2O3:Eu3+ nanopowders via polymer complex solution method and luminescence properties of the sintered ceramics

“…7 F 1 transition is the parity-allowed magnetic dipole transition (DJ = 1) and its intensity does not vary with the host. On the contrary, the 5 (DJ = 2) is very sensitive to the local environment around Eu 3+ , and its intensity depends on the symmetry of the crystal field around the europium ion. The asymmetry ratio of the integrated intensity of the 5 D 0 !…”

“…Among them, oxide phosphors are found to be suitable for field emission (FED), vacuum fluorescent (VFD), electroluminescent (EL) and plasma panel (PDP) display devices. Phosphors based on Eu 3+ doped rareearth (RE) sesquioxides, such as yttrium and gadolinium oxides, are well-known materials widely used to provide red light emission for modern optoelectronic devices and their investigation is still of great interest [2][3][4][5][6]. Regarding phosphors for scintillating applications they are the first choice for sintered scintillators [7].…”

X‐ray diffraction analysis of powder and thin film of (Gd1‐xYx)2O3 prepared by sol‐gel process

“…Both are promising materials for electronic applications to replace SiO 2 in metal-oxide-semiconductor (MOS) heterostructures used in the MOS transistor [6]. In addition, pure and doped Gd 2 O 3 films have been studied as catalyst for dimerization of many organic compounds [7], phosphor films [8,9], scintillating films [10] and to passivate III-V compound semiconductors [11]. As optical waveguides, Y 2 O 3 films is a promising candidate of low propagation loss [12][13][14].…”

Characterisation of oxidised gadolinium film deposited on Si (100) substrate

“…Consequently, the FTIR study has focused on the vicinity of the absorption band of Gd 2 O 3 , which is around 559 cm −1 as reported in refs. [16,56,57] and graphically recorded in ref. [58].…”
