Abstract: The temperature dependence of the luminescence of Ca2YSbO6: RE3+ (RE=Sm, Eu, DY, Ho, Er) phosphors was determined by irradiating the Thosphor by a mercury-xenon discharge lamp. For all phosphors investigated except Ca2YSbO6: Er the intensity of luminescence in general was decreased with increase of temperature and was quenched at last at 300-400℃. A gualitative explanation is given to the temperature quenching of Ca2YSbO6: RE3+. The emisson spectra of the sample under different temperature would be useful in finding the luminescent powder for high-pressure mercury discharge lamp.
