In this work, we aim to fabricate a highly stable and flexible perovskite paper photodetector based on a Zn-doped MAFAPbI perovskite and CNC. The paper photodetector has been successfully synthesized by the vacuum filtration method and deposited with interdigitated electrodes. The paper photodetector exhibits a significant photoresponse with a responsivity of 0.

In the present investigation, free-based tetraphenyl porphyrin (TPP) and iron tetraphenyl porphyrin (FeTPP) are used to functionalize thermally reduced graphene oxide (rGO) and further used for the detection of carbon monoxide (CO). TPP and FeTPP functionalized rGO (FeTPP@rGO) sensors are fabricated on a glass substrate with thermally coated copper electrodes.

- Inorganic perovskite quantum dots (IPQDs), like cesium lead halide, are promising for cadmium-free quantum light-emitting displays due to their excellent light emission properties, including high photoluminescence quantum yield and adjustable bandgap.
- A new method using sulfate-functionalized cellulose nanocrystals is introduced to enhance the stability of CsPbBr IPQDs, achieving significant improvements without traditional stabilizers.
- The resulting hybrid films show remarkable stability under various conditions, maintaining up to 92% photoluminescence intensity after prolonged UV exposure and over 99% at high temperatures and ambient conditions, making them viable for future IPQD-related applications.
