Abstract:
A method for rapid identification of uranyl compounds based on resonance fiber-optic photoluminescence (PL) excitation by ultraviolet-laser or LED radiation is proposed. This method was used to measure the PL spectra of an extremely small volume (10$^{-9}$ cm$^3$) of crystalline uranyl acetate dehydrate UO$_{2}$(CH$_{3}$COO)$_{2}$ $\cdot$ 2H$_{2}$O with an exposure of 10$^{-3}$ s. Semiconductor LEDs with wavelengths of 369, 385, 410, and 466 nm and a repetitively pulsed nitrogen laser with a lasing wavelength of 337 nm served as sources of excitation radiation. The operating range of a small-sized minispectrometer used in these experiments was 200–1000 nm.
