The intriguing coupling interactions between photochromism and ferroelectric polarization were firstly observed in Sm doped (K0.5Na0.5)NbO3 piezoceramics. After 407 nm irradiation, the maximum polarization (Pmax) and remanent polarization (Pr) intensities were dramatically decreased, whereas the coercive field, leakage current and photocurrent showed the remarkable increase. The variations of the polarization and photocurrent can be reversibly converted by alternating light irradiation and thermal stimulus, suggesting good polarization switching performance. This work provides a new route to effectively modulate ferro-/piezoelectric and photocurrent properties of ferroelectric materials by the non-contact remote control of light.

Photonics is a subject of scientific study on generating, controlling, harvesting and detecting the beam of photons or light with a purpose of creating, manipulating, storing, transmitting and detecting information using nonlinear optical properties of materials. This paper is a new attempt to integrate scientific research and social research by analysing the characteristics of dye-doped polymer films for photonics applications. The analysing framework called ABCD framework to analyse any business concepts, business systems, technology, strategy, engineering material, technology or even an idea systematically by identifying the advantages, benefits, constraints, and disadvantages under various determinant issues and listing the constituent critical elements under each construct. In this paper, as per the ABCD framework, the various determinant issues related to the use of dye-doped polymer films for photonic applications through focus group method are determined as affecting factors under : (1) Material Issues, (2) Application Issues, (3) Commercialization Issues, (4) Production/Service providers Issues, (5) Customer Issues, and (6) Environmental/Social Issues. The constituent critical elements of these factors are listed under the four constructs - advantages, benefits, constraints and disadvantages of the ABCD technique and tabulated. The analysis has brought about 204 critical constituent elements which satisfy the success of this analysis methodology.
