AB  - In this work, the Eu(3+)doped stuffed tridymite type structure of alkaline earths 
      aluminate i.e. XAl(2)O(4)(X = Mg, Ca, Sr and Ba) phosphor materials have been 
      synthesized by conventional high temperature solid state reaction method at 1623 
      K. The Samples were structurally and morphologically characterized by x-ray 
      diffraction (XRD) and Scanning electron microscope (SEM) measurements. The 
      vibrational behavior of the phosphor samples were investigated by Fourier 
      transform infrared (FTIR) measurements. The phosphor samples emit intense red 
      emission in 610-615 nm range due to(5)D(0) --> (7)F(2)transition of Eu(3+)ion on 
      excitation with charge transfer band (CTB) wavelength arising due to 
      Eu(3+)-O(2-)and also by the discrete bands of Eu(3+)ions .The decay time 
      of(5)D(0)level of Eu(3+)ion were recorded on excitation with 393 nm and by the 
      CTB wavelength for all the four samples. The optimized 1 mol% Eu(3+)doped 
      CaAl(2)O(4)phosphor exhibits optimum emission intensity and color purity under 
      the excitation with 393 nm than others. The decay time is also found to be larger 
      in the case of Eu(3+)doped CaAl(2)O(4)phosphor sample. Therefore, Eu(3+)doped 
      CaAl(2)O(4)phosphor may be promising material for red color light emitting 
      applications and white light generation.
