Developing a reliable technique to measure two-dimensional temperature profiles of gas flows is significantly profitable for the development of advanced thermal devices, but is also one of the most challenging subjects. In an attempt to develop such a reliable and two-dimensional gas temperature measurement technique, we are developing the planer laser-induced fluorescence (PLIF) using fluorescences from two fluorescent materials. One of fluorescent material is used as a reference of laser intensity. The advantage of this technique is that it supposedly reduces the error due to the nonuniformity of laser intensity profile. As a first stage of this development, the temperature dependence of the fluorescence spectrum from ethylbenzene doped into N2 gas induced by the fourth harmonic (266nm) of Nd:YAG laser is investigated in the present paper.
