研究目的
to analyze in detail the luminescent properties of undoped strontium aluminate nanocrystals synthesized by sol-gel method, and the effect of irradiation with beta particle in the TL and OSL response, verifying the Minimum Detectable Dose (MDD) for OSL and TL, since there is no similar study in undoped strontium aluminate.
研究成果
Nanocrystals of SrAl2O4 monoclinic and Sr12Al14O33 cubic phase were successfully synthesized by sol-gel method, exhibiting complex TL and high OSL intensities. The study provides detailed analysis of luminescent properties and establishes MDD values for potential applications in dosimetry.
研究不足
The study focuses on undoped strontium aluminate, and the luminescent properties may vary with doping. The MDD values are specific to the experimental conditions used.
