Here, a new promising “black” surface Ti<sub>3</sub>O<sub>5</sub> ceramic with semiconductor–metal phase transition has been discovered through experimental demonstration and density functional theory calculation on three types of phases for Ti<sub>3</sub>O<sub>5</sub> at various temperatures. The Ti<sub>3</sub>O<sub>5</sub> ceramic displayed low and temperature-dependent reflectivity in the ultra-wideband.

The observed temperature-dependent tunability in terms of ultra-broadband low-reflectivity (0.25–16.0 µm) arises from sequential phase transitions from β–Ti<sub>3</sub>O<sub>5</sub> to λ–Ti<sub>3</sub>O<sub>5</sub> and finally to α–Ti<sub>3</sub>O<sub>5</sub>. Additionally, the mechanism of the Ti─O bond for temperature-dependent emissivity is proposed by combining the orbital characteristics of the density of states and phononic structures. Furthermore, a composite PE/Ti<sub>3</sub>O<sub>5</sub>/Al<sub>2</sub>O<sub>3</sub> exhibited 37% reduced solar absorptivity while maintaining high infrared emissivity (∼0.92), confirming Ti-O bonds dominate emissivity properties rather than structural modifications.

This study introduces a novel approach to light dispersion utilizing a bandgap-graded semiconductor film, synthesized through a streamlined material preparation process. The film's intrinsic transmission properties enable effective light dispersion without the limitations imposed by optical interference, making it ideal for integration into miniaturized optical devices.
