In this work, TeO_(0.7)thin films were prepared by the reactive magnetron-controlling sputtering method. Complex gray-scale patterns were successfully fabricated on TeO_(0.7)thin films through the laser direct writing method.The structural origin of TeO_(0.7)thin film was investigated for gray-scale pattern formation. It is found that multiple gray-scale levels are dependent on the “virtual” bandgap energy of TeO_(0.7)thin films. The bandgap energy changes lead to refractive index and reflectivity difference. Thus, gray-scale tones can be formed. By accurately controlling laser energy, various “virtual” bandgaps can be generated in TeO_(0.7)thin films, and colorful gray-scale levels can be formed. Experimental results indicate that TeO_(0.7)thin film can be used as micro/nano image writing material.
