The emission of Er3+ provides three combinations bands suitable for ratiometric luminescence thermometry. Two utilize ratios visible emissions (2H11/2→4I15/2 at 523 nm/ 4S3/2→4I15/2 542 nm and 4F7/2→4I15/2 485 545 nm), while from the third combination are located in near-infrared, e.g., first biological window (2H11/2→4I13/2 793 4S3/2→4I13/2 840 nm). Herein, we aimed to compare thermometric performances these different readouts on account their relative sensitivities, resolutions,...
Phosphors for luminescence thermometry La 1− x Ga 0.99 O 3 :Cr 0.01 , Nd were synthesised by the solid-state method, structurally characterised using powder X-ray diffraction data, and investigated ambient variable-temperature optical measurements.
Front-face synchronous fluorescence spectroscopy combined with chemometrics is used to classify honey samples according their botanical origin. Synchronous spectra of three monofloral (linden, sunflower, and acacia), polyfloral (meadow mix), fake (fake acacia linden) types (109 samples) were collected in an excitation range 240–500 nm for wavelength intervals 30–300 nm. Chemometric analysis the gathered data included principal component partial least squares discriminant analysis. Mean...
Abstract The introduction of additional functionalities to materials is exceptionally important as it opens new applications for them. Aluminum, one the most abundant and materials, coated with luminescent Sm 2+ ‐doped γ‐aluminium oxide impart thermometric functionality. Considering potential industrial applications, two widely used aluminum alloys, 6061 7075, are also coated. For this purpose, plasma electrolytic oxidation (PEO), an effective technique producing hard ceramic coatings on...
Honey is a frequent target of adulteration through inappropriate production practices and origin mislabelling. Current methods for the detection adulterated honey are time labor consuming, require highly skilled personnel, lengthy sample preparation. Fluorescence spectroscopy overcomes such drawbacks, as it fast noncontact requires minimal In this paper, application fluorescence coupled with statistical tools demonstrated. For purpose, excitation-emission matrices were measured 99 samples...
In recent years, the potential of Fourier-transform infrared spectroscopy coupled with different chemometric tools in food analysis has been established. This technique is rapid, low cost, and reliable requires little sample preparation. this work, 130 Serbian unifloral honey samples (linden, acacia, sunflower types) were analyzed using attenuated total reflectance (ATR-IR). For each spectrum, 64 scans recorded wavenumbers between 4000 500 cm−1 at a spectral resolution 4 cm−1. These spectra...
Over the years various optical spectroscopic techniques have been widely used as diagnostic tools in discrimination of many types malignant diseases. Recently, synchronous fluorescent spectroscopy (SFS) coupled with chemometrics has applied cancer diagnostics. The SFS method involves simultaneous scanning both emission and excitation wavelengths while keeping interval (constant-wavelength mode) or frequencies (constant-energy between them constant. This is fast, relatively inexpensive,...
The paper presents the results of experimental and theoretical study 3,3′-disulfopropyl-5,5′-dichlorothiacyanine sodium salt (TC) adsorption J-aggregation on surface citrate-capped silver nanoparticles (AgNPs) with an average particle size 10 nm. Various nanospectroscopy techniques such as UV–vis, TEM, AFM, DLS, ζ potential, fluorescence measurements were carried out in order to characterize hybrid system. Besides this, a set simple density functional theory calculations (DFT) was performed...
