Pulsed laser deposition of ZnGa2O4 phosphor films

Microstructure-dependent luminescent properties of thin-film ZnGa2O4:Mn2+ phosphors

“…It indicates that the crystallinity is gradually enhanced with increasing the temperature. It is well known that the crystallinity of phosphor directly influences the luminescent intensity [13]. So the enhanced crystallinities of our film phosphors by higher-temperature annealing will cause to increase the luminescent intensity as confirmed by the following PL spectra.…”

Fabrication of BCNO-composite thin film phosphors and controlling its thickness

“…Because of longterm stability, high image resolution, thermal stability, good heat resistance, and superior adhesion to the substrate, film type phosphors are more applicable than powder form [1]. Film phosphor technology can be used in many applications, such as: photoluminescent LCDs, field emission displays, cathode ray tubes, plasma display panels, electroluminescent displays, wavelength converter in solar cell, and other optoelectronic devices [1][2][3] Phosphor film can be synthesized by using several methods such as: sputtering deposition [4], pulsed layer deposition [5], atomic layer deposition [6], spray pyrolysis [7], and chemical vapor deposition [8]. However, these methods require complicated and expensive equipment since need a vacuum condition.…”

Microwave‐Hydrothermal Synthesis of Nanostructured Zinc‐Copper Gallates

“…[21] The properties of zinc gallates in general are a function of their preparation and of the resulting morphology, such as nanowires, [12,22,23] polyhedron-related, rod-like or irregular shapes. [24] The prevailing synthetic approaches to pristine and substituted ZnGa 2 O 4 materials are solid-state reactions, [5,7,13,20,[25][26][27] sol-gel methods, [18,28,29] pulsed laser deposition techniques, [30] co-precipitation, [7] chemical transport, [31] thermal evaporation, [12,22,23,32] the Pecchini approach [19] and hydrothermal methods [24,26,27,[33][34][35][36][37] (for a survey see Supporting Information, Table S.1). Among these techniques, hydrothermal syntheses are of special interest, because they can provide homogeneous phases and particle size distributions as well as tuneable particle morphologies in a single reaction step.…”
