Study of optically stimulated luminescence of Tb3+/Sm3+ doubly doped K2YF5 single crystals

Caracterización de materiales luminiscentes tejido-equivalentes para la detección de radiación ionizante

“…Since learning about the OSL spectrum is crucial in order to determine the optimal combination of filters and LEDs to maximize the collection of emitted light, and since the OSL emission is not stationary, a good alternative is obtaining the RL emission spectrum (Marcazz� o et al, 2011). Thereby, the emission wavelength depends on the recombination centers and it is expected that the luminescence centers involved in OSL are likely the same participating in the RL mechanism (Marcazz� o et al, 2013(Marcazz� o et al, , 2015. Although the luminescence centers which participate in both the RL and OSL signal are not always the same for all materials, this is usually the case when the process of stimulation and recombination occurs through the conduction band (Marcazz� o et al, 2015).…”

“…The luminescence properties of several rare earth doped potassium yttrium fluoride have been studied earlier (Faria et al, 2004;Kui et al, 2006;Marcazzó et al, , 2013Marcazzó et al, , 2015 and it has been found that their luminescent properties make these materials promising for use in dosimetry.…”
