Abstract
The 4I15/2-6H15/2 and 4F9/2-6H15/2 transitions of Dy3+ are usually used for luminescent ratiometric thermometry in the form of photoluminescence. However, here we demonstrate the possibility of using this pair of lines for luminescent ratiometric thermometry in the model of mechanoluminescence (ML) in CaZnOS:Dy3+. Upon stimulation of an external mechanical force rather than light, CaZnOS:Dy3+ emits bright yellow luminescence. The intensity ratio of 4I15/2-6H15/2 to 4F9/2-6H15/2 transitions of Dy3+ is found to increase gradually with the rise of temperature, which makes Dy3+ a qualified temperature indicator. Our work enriches the family of optical thermometry.
