EDITORIAL NOTE

We are happy to bring out this second volume of the Departmental journal, Journal of Physics Research and Education. We apologize for the inordinate delay in bringing out this volume. We aim to publish a new volume regularly in every year. The goal of JPRE is to have an amalgamating impact for the diversity of the fields of physics research and physics education. The current volume has a distinctive aspect of this nature contributed together by Ph.D. scholars, Post doctoral scholars and Professors. I hope this volume will reflect the current state of interdisciplinary research, insightful reviews and will indicate the usefulness of their material to physics education.

    Flexible Piezoelectric Energy Harvester Based on UV Light Emitting Ce3+-Complex-P(VDF-HFP) Composite Films
    (University of North Bengal, 2024-03) Barman, Priti Sundar; Adhikary, Prakriti
    In this study, we report on the preparation of a polymer composite film with enhanced ( 99%) electroactive phases - and -phase) based on P(VDF-HFP) copolymer and Ce3+-complex. Furthermore, its utilization in piezoelectric-based flexible energy harvesting (PFEH) device fabrication has been studied, where the electrostatic interactions between the surface charges of Ce3+-complex and -CH2-/-CF2- molecular dipoles of P(VDF-HFP) via H-bonding co-operate to stabilize the electroactive phases and enhance its piezoelectric properties. PFEH generates 3 V of open circuit voltage and 0.16 A short-circuit current under the external pressure impacting amplitude of 14.20 kPa. Moreover, it can successfully charge up capacitor by repeating finger impact which indicates its potency as an efficient energy-harvesting device. Besides this, the composite film exhibits an intense photoluminescence in the UV-region that might be very promising in the area of high-performance, energy-saving, flexible, solid-state UV light emitters and fabrication of hybrid multifunctional energy harvester where mechano-luminescence phenomenon might be possible to include.
