Phosphor fluorescence
WebThe Pr3+-doped NaY (MoO4)2 phosphor is a high-performance material that can be employed for refined calibration and temperature measurements according to the two-group schema defined by fluorescence intensity ratio. WebAug 25, 2016 · The changes in fluorescence are often attributed to a shortened bond length between atoms in a strengthened crystal field, resulting in a shift in the associated energy levels. For such sensing applications, a wavelength shift at the intensity maximum of the emission peak (s) of a phosphor is normally used as the sensing element.
