Photostrictive actuators and its some characteristics

The characteristics and its process technology of the photostrictive materi als were taken into consideration from the material view of points. Lead la nthanum zirconate titanate bulk ceramics has been the only material for the se photostrictive applications. But gas deposition method was proved to be one of the useful process techniques for the production of these actuators. The formed film has the same crystal structure before and after of the for mation process of the gas deposition method. On the other hand the waveleng th dispersion of the absorption coefficients of the bulk ceramics was exami ned. The validity of the wavelength, which has been used, was proved throug h knowledge of the wavelength dispersion of the absorption. Some proposal w as shown for the development of this character from the material view of po ints.
