The steady-state temperature-dependent fluorescence of (Ba,Sr)2SiO4∶Eu2+ is studied, under an excitation at 405 nm. After the raise of two novel sensing methods, barycenter technique and intensity ratio technique for wide band emissions, multiple sensing functions are retrieved, using the behaviors of wavenumber/wavelength of emission band barycenter, emission bandwidth, and ratios of intensities at different wavelengths in the emission band, respectively. All the four kinds of functions demonstrate nearly linear relationship with temperature in the measurement range. The sensing mechanisms are briefly discussed. The phosphor′s multi-functional temperaturesensing abilities can be taken advantages of for use as a point thermometer for a variety of applications.
