Energy-saving glass is realized using nano-imprinting to fabricate a periodic nano-structures. The glass can suppress the transmission of ultraviolet light such that people are not harmed. The transmission of infrared is largely reduced to lower air-conditioning. On the other hand, transmission is not deteriorated in the visible range to prevent the increment of illumination cost.

A wavelength tunable micro-light-emitting diodes fabricated by the nanometer-level etching technology, the strain-induced engineering can effectively shift the emission wavelength from green to blue. Meanwhile, we introduced the ALD for the passivation layer,the super inkjet printing system used to form the color-conversion layer to emissive red light. Finally, a hybrid type full-color micro-LED has been fabricated with the monolithic epitaxial wafer.
