“…At present, most LAPs are prepared by high temperature solid phase method, which has the disadvantage of being unable to control the particle morphology of materials. The samples prepared are usually severely agglomerated and cannot be uniformly coated, which restricts their further expansion and application [10,11]. The apparent structure of materials, such as morphology and size, has a significant impact on the luminescent properties of materials.…”

Due to the special optical properties of rare earth elements, rare earth luminescent materials have been widely used in lighting, medical radiological images, detection and recording of radiation field and other fields. Through the research and analysis of phosphate LaPO4:(Ce3+,Tb3+), Ca9Y (PO4):(Ce3+,Tb3+), GdPO4:(Ce3+,Tb3+) composite materials by the hydrothermal preparation of cerium-terbium co-activated, the hydrothermal preparation process (additives, reaction system pH, hydrothermal time, hydrothermal temperature, etc.), luminescent properties and application status were clarified. XRD and SEM were used to analyze the effect of hydrothermal preparation process on the phase composition and morphology of samples, and the energy transfer efficiency was determined. PL spectroscopic analysis shows that the 4f→5d and 5D4→7Fj (j=6,5,4,3) transitions in Ce3+-Tb3+ UV region have been demonstrated in a variety of matrix materials, enabling efficient energy transfer in co-doped ion combinations., and the concentration of doping ions will significantly affect the luminescence properties.

“…Functional coating materials play an indispensable role in improving the wear resistance of enginebearing shells. The aluminum particles reinforced functional coating has good development potential, but there is still room for further development of the coating's adhesion, thermal shock, wear resistance, and corrosion resistance [1][2][3].…”

In view of the upgrading of engine-bearing pad-coating materials, the preparation of functional coatings suitable for bearing pad surfaces sprayed with aluminum particles as the reinforcing phase has important application value. In this paper, the exploration of preparing composite coatings on the working surface of bearing pads with aluminum particles as the reinforcing phase was carried out through orthogonal experiments. The effects of different process parameters on the adhesion, bonding strength, and micro-hardness of the coatings during the preparation process were studied, which provided a theoretical basis for the preparation of functional coatings.

Herein, it is reported on calculating thermoluminescence (TL) kinetic parameters determined from the TL emission of synthetic GdAlO3 (GAO) phosphors prepared by the coprecipitation method. The sample characterized employing X‐ray diffraction with an orthorhombic phase structure (space group Pnma (62)) shows complex glow curves consisting of at least four groups of components peaked at 100, 140, 240, and 290 °C where the two lower overlapped temperature peaks are difficult to identify using the TM‐Tstop. The coexistence of a continuum in the trap distribution (linked to the lower temperature peaks) and a discrete trap system (associated with the components at temperatures higher than 200 °C) can be distinguished. The estimation of the TL kinetic parameters is performed using GlowFit, computing glow curve deconvolution (CGCD), and various heating rate methods. However, only CGCD appears as the suitable technique for such purpose since it provides information on the TL physical process supported by mathematical models based on a linear combination of functions related to the first order kinetic approach.
