dc.description.abstractLa importancia de este trabajo se basa en encontrar la mejor respuesta termoluminiscente de la síntesis por el método de reacción de estado sólido del compuesto LiF con incorporaciones de NdF3, CeF3 y LaF3. De esta manera, se encuentran por medio de los difractogramas la coexistencia de dos fases de manera independiente del LiF y las incorporaciones de NdF3, LaF3 y CeF3 del 2%, 6% y 12% respectivamente, variando entre ellas la intensidad y el ancho de los picos característicos, de tal manera que la intensidad de los picos tiene relación directa con la respuesta termoluminiscente, donde la absorción de radiación implica una disminución de la intensidad de la señal. Se encuentran los coeficientes de electrones retrodispersados para el LiF de η = 46.7%, para la incorporación del 2% de NdF3 es de η = 6.0%, para la incorporación del 6% de LaF3 es de η = 25.8% y para el CeF3 es de η = 21.4%. Este factor es importante para la absorción y almacenamiento de radiación ionizante. De esta manera se encuentra solamente respuesta termoluminiscente bajo radiación rayos X de 1KeV para el caso de la incorporación del NdF3 obteniendo la mejor respuesta para el caso del 2% y un pico máximo de emisión 2μA, LiF un pico máximo de emisión de 74nA. Por último, se encontraros respuestas TL máximas bajo radiación UV-C de 25nA para el LiF, 310nA para el 2% NdF3, 152nA para el 6% LaF3 y de 47nA para el 2% CeF3. (Texto tomado de la fuente).
dc.description.abstracthe importance of this work is based on finding the best thermoluminescent response of the synthesis by the solid state reaction method of the LiF compound with incorporations of NdF3, CeF3 and LaF3. This way, the coexistence of two phases independently of LiF and the incorporations of NdF3, LaF3 and CeF3 of 2%, 6% y 12% respectively, varying between them the intensity and width of the characteristic peaks. respectively, are found by means of the diffractograms, varying between them the intensity and width of the characteristic peaks, in such a way that the intensity of the peaks is directly related to the thermoluminescent response, where the absorption of radiation implies a decrease in the intensity of the signal. The coefficients of backscattered electrons for LiF are found to be η = 46.7%, for the incorporation of 2% NdF3 it is η = 6.0%, or the incorporation of 6%, LaF3 it is η = 25.8% and for CeF3 it is η= 21.4%. This factor is important for the absorption and storage of ionizing radiation. In this way, only thermoluminescent response is found under 1KeV X-ray radiation for the case of NdF3 incorporation, obtaining the best response for the case of 2% and a maximum emission peak of 2μA, LiF a maximum emission peak of 74nA. Finally, maximum TL responses under UV-C radiation of 25nA for LiF, 310nA for 2% NdF3, 152nA for 6% LaF3 and 47nA for 2% CeF3 were found.
