| Библиографическое описание на языке оригинала |
Sidorov, I. D., Oleynikova, E. I., Pudovkin, M. S., Nizamutdinov, A. S., Semashko, V. V., Gafurov, M. R., ... & Komlev, V. S. (2024). Spectral and kinetic characteristics of precipitated and heat-treated hydroxyapatite and tricalcium phosphate doped with europium. Optical Materials, 116609. |
| Аннотация |
Synthetic calcium hydroxyapatite (HA) and tricalcium phosphate (TCP) doped with Eu3+, exhibiting photoluminescence in the spectral range between 550 and 750
nm, are promising optical markers in application of bioimaging due to their biocompatibility, adsorption capacity for proteins, and good stability during storage.
Eu-doped HA and TCP precipitates were synthesized via wet precipitation technique and then heat-treated at 1300 ◦C. The precipitates and heat-treated powders
were studied using X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic emission spectrometry (AES), and luminescence spectroscopy. A
comparative analysis of the luminescence spectra revealed the intensity increase as a result of heat-treatment for both Eu-doped HA and TCP under excitation at 266
and 394 nm. The characteristic emission for Eu3+ due to 5
Di→7
Fj transitions were detected. The changes in the intensity, shape and position of the spectral lines,
depending on the phase composition, synthesis conditions and excitation conditions, were demonstrated. The measurement of photoluminescence quantum yield and
assessment of kinetic characteristics showed the difference of Eu3+ luminescence in HA and TCP matrices due to the effect of the Eu3+ crystal field within the matrix.
A linear temperature dependence of luminescence decay time was observed in wide temperature range, making the obtained materials highly promising for tem
perature sensing applications. |
