Development of SrWO:Ho/Yb green phosphor for optical thermometry application.

In recent years, the growth of luminescent materials for optical thermometry applications has gained substantial attention due to their non-invasive and contactless nature. This research article presents the synthesis, characterization, and potential application of SrWO:Ho/Yb phosphors as temperature-sensitive materials. The inspection of the structural properties is done by X-ray diffraction and Raman and FTIR spectroscopy.

An attempt to enhance the afterglow luminescence of NIR light emitting long persistent phosphor ZnGaGeO:Cr by Pr co-doping.

In this study we have focused on the improvement of luminescence intensity and the long afterglow luminescence of Cr doped ZnGaGeO long persistent phosphor by adding an appropriate amount of Pr ions in proportion with Ga concentration. We have successfully developed a series of long persistent ZnGaCrPrGeO (where x = 0, 0.04 and y = 0, 0.
