“…The characteristic emission centred at 489 nm corresponds to 4 F 9/2 → 6 H 15/2 and 567 nm corresponds to 4 F 9/2 → 6 H 13/2 . The blue emission is due to the magnetic dipole interaction whereas the yellow emission is due to the electrical interaction [16].…”

Dysprosium (Dy 3+) ion-doped GdAlO 3 nanophosphors were fabricated by using a high temperature solid state reaction method. X-ray diffraction measurements were used to investigate the phase and crystal size of these phosphors. The morphology of the powder was observed by scanning electron microscopy. The band structure of the phosphor was determined by recording the UV absorption spectra and Tauc plot. The optical behaviour of the phosphors was determined by measuring their photoluminescence (PL) spectra. The PL spectra show characteristic blue (489 nm) and green (567 nm) emissions corresponding to the energy level transitions of Dy 3+ .

Spray Pyrolysis Technique; High-K Dielectric Films and Luminescent Materials: A Review

2018

View full text Add to dashboard Cite

The spray pyrolysis technique has been extensively used to synthesize materials for a wide variety of applications such as micro and sub-micrometer dimension MOSFET´s for integrated circuits technology, light emitting devices for displays, and solid-state lighting, planar waveguides and other multilayer structure devices for photonics. This technique is an atmospheric pressure chemical synthesis of materials, in which a precursor solution of chemical compounds in the proper solvent is sprayed and converted into powders or films through a pyrolysis process. The most common ways to generate the aerosol for the spraying process are by pneumatic and ultrasonic systems. The synthesis parameters are usually optimized for the materials optical, structural, electric and mechanical characteristics required. There are several reviews of the research efforts in which spray pyrolysis and the processes involved have been described in detail. This review is intended to focus on research work developed with this technique in relation to high-K dielectric and luminescent materials in the form of coatings and powders as well as multiple layered structures.

ZrO2 and ZrO2:Sm3+ nanopowders are synthesized by means of polyol method, from [Zr(NO3)2.xH2O] and (SmCl3·6H2O) precursors dissolved in a diethylene glycol medium. X‐ray diffraction (XRD) results show polymorphic powders because monoclinic structure and tetragonal are exhibited. The crystal size is estimated by Scherrer formula; an averaged crystallite size of 9 nm is obtained. Surface morphology study, by means of SEM, evidences multiform particles, some with straight edges associated with monoclinic or tetragonal structure. The chemical composition microanalysis results indicate agreement with ideal stoichiometry for ZrO2 and ZrO2:Sm3+ powders. The photoluminescence emission spectra show that maximum intensity is reached at λ = 614 nm due to transition 4G5/2→6H7/2, exciting with λex = 240 nm, which corresponds to sample ZrO2:Sm3+ (0.75 at%); this sample is labeled as M3. Very similar results are obtained by cathodoluminescence studies. On the contrary, exciting with λex = 380 nm (monitoring emission band peaked at 614 nm), emission bands of host lattice and ZrO2:Sm3+ are favored simultaneously. The luminescent quenching phenomenon occurs when doping concentration (Sm3+ ions) is >=0.75 at%. The photoluminescent emission exhibits a reddish orange color, characteristic of Sm3+ ions, and yellowish‐orange for cathodoluminescence emission.
