Reversible modification of the ultra-broadband luminescence in transparent photonic materials through field-induced nanoscale structural transformation
The development of integrated multifunctional materials with transparent characteristics meets the requirements of optoelectronics and communication. The coupling of stimuli-responsive materials has become a frequently considered strategy. Experimentalists not only search for photonic materials with excellent physical and chemical properties, but also pursue precise and reversible spectral modification. In this article, the luminescent center Ni2+ is artificially introduced into the into transparent LiNbO3 nanoferroelectric photonic materials. The Ni2+ ions-based transparent photonic materials exhibits novel complete the ultra-broadband emission in the whole near-infrared region. The ultra-broadband emission was up to now realized by codoping of several active doping ions. In addition, the emission intensity and wavelength of the luminescent center are modified accurately and reversibly by the field-induced nanoscale structural transformation. The Ni2+ ions-based transparent nanoferroelectric photonic materials provide an easy way to approach the tunable lasers operating and ultra-broadband optical amplifier in the near-infrared band.
