Thermoluminescence of ZnS doped with Dy and Mn

Luminescence in Zinc Selenide Doped with Sn and (Sn, Dy) Phosphors

“…The values of activation energy E corresponding to different peaks for these phosphors have been calculated by employing Curie's relation [15][16][17]21]…”

“…[ [15][16][17] and is tabulated in Table 2. The capture cross-section (𝜎) of the electron was calculated by the well-known Mott-Gurney [15][16][17] and obtained value is tabulated in Table 2, which is the order of 10 −22 m 2 for all election traps in all cases. It is obvious that as trap depth increases, cross-section values decrease.…”

“…The frequency factor has been calculated by using well known Randall and Wilkins relation [15][16][17] and the values are tabulated in Table 3.…”

“…Trapping parameters trap depth, the lifetime of the electron in trap-depth, frequency factor, and area of cross-section of the electron has been calculated by using Curie and peak-shift methods. [15,16,17,21]…”

“…An important application of TL solid state dosimetry of ionizing radiation for the dating of archaeological and geological specimens. [13][14][15][16][17]18,19,[20][21][22]11,12] Zinc selenide doped with Sn and (Sn, Dy) has been researched due to its scientific and commercial significance. The present paper focuses on photoluminescence (PL), EL, and TL) studies of the synthesized ZnSe: Sn and ZnSe: (Sn, Dy) phosphors as fine crystalline powders.…”
