We have synthesized a lead-free stable organic-inorganic perovskite (MA2CoBr4) by using non-hazardous solvents such as methanol and ethanol, which are eco-friendly and safe to handle in comparison to DMF, toluene, etc. Single crystals of MA2CoBr4 were grown using a simple solution technique, and their electrochemical oxygen evolution was investigated in a wide pH range.

The present investigation provides an easy and affordable strategy for fabrication of functional ceramics BiNaTiO-SrFeO (BNT-SrF5) thick films on a flexible, inexpensive and electrically integrated substrate using electrophoretic deposition process (EPD). EPD is a widely accepted, environmentally friendly method for applying coatings from a colloidal suspension to conductive substrates. Lead-free ferroelectric BNT-SrF5 powder was synthesized by solid state method to fabricate bulk samples and thick films (30-160 μm) by EPD process.

The development of efficient color conversion layers for μ-LED technology faces significant challenges owing to the limitations of materials that require binders. Binders are typically used to ensure uniform film formation in color-conversion layers, but they often cause optical losses, increase layer thickness, and introduce long-term stability issues. To address the limitations of materials requiring binders, cyclopropyltriphenylphosphonium manganese tetrabromide (CPTPMnBr) is synthesized, a novel lead-free metal halide.

Piezoelectric materials are increasingly used in portable smart electronics and Internet of Things sensors. Among them, piezoelectric macro fiber composites (MFCs) have attracted much attention due to their architectural simplicity, scalability, and high-power density. However, most MFCs currently use toxic lead-based piezoelectric materials, hindering their applications for bio-friendly intelligent electronics.

Perovskite-based photodetectors (PDs) are broadly utilized in optical communication, non-destructive testing, and smart wearable devices due to their ability to convert light into electrical signals. However, toxicity and instability hold back their mass production and commercialization. The lead-free Cs2AgBiBr6 double perovskite film, promised to be an alternative, is fabricated by electrophoretic deposition (EPD), which compromises film quality.

Relaxor ferroelectric film capacitors exhibit high power density with ultra-fast charge and discharge rates, making them highly advantageous for consumer electronics and advanced pulse power supplies. The Aurivillius-phase bismuth layered ferroelectric films can effectively achieve a high breakdown electric field due to their unique insulating layer ((BiO) layer)). However, designing and fabricating Aurivillius-phase bismuth layer relaxor ferroelectric films with optimal energy storage characteristics is challenging due to their inherently stable ferroelectric properties.
