Impact of Ag Co-doping on photoluminescence of Ce-doped sodium borate glasses Sonia Kaur, Nancy Mahendru, Jatinder Kaur, K Basanth Kumar, Chetansinh R Vaghela, K Parasuraman, Indu Gupta, Shivani Singla Physica Scripta, 2026 This study investigates the structural, optical, and photoluminescent properties of Ce-doped sodium borate glasses co-doped with silver, synthesized via the melt-quenching technique. X-ray diffraction (XRD) and Fourier-transform infrared (FTIR) analyses confirm the amorphous nature of the glass matrix and reveal the presence of both BO 3 and BO 4 structural units. High-resolution transmission electron microscopy (HRTEM) provides direct evidence of metallic silver nanoparticle formation, with average sizes increasing from ∼2 nm in Ag-doped glass to ∼8 nm in Ag+Ce co-doped glass, suggesting that Ce co-doping influences Ag nucleation kinetics. UV-Visible absorption spectra show a distinct surface plasmon resonance (SPR) band for Ag glass at ∼417 nm, which is suppressed in the co-doped sample due to Ce-ion absorption . A significant redshift in the optical absorption edge and a reduction in the bandgap (E opt ) from 3.11 eV to 2.60 eV are observed upon doping, attributed to the formation of non-bridging oxygens. Photoluminescence (PL) spectra under 320 nm excitation exhibit intense blue emission for Ce-doped glass (5d to 4f transitions), which is significantly quenched in Ag-containing samples due to non-radiative energy transfer and LSPR-induced losses. CIE chromaticity analysis demonstrates color tunability from near-white to deep-blue regions, highlighting the potential of these glasses for specialized solid-state lighting applications.
Fine-Tuning T5 and BERT for Effective Question Answering and Document Retrieval: A Transfer Learning Approach Mratyunjay Tiwari, Jatinder Kaur, Ram Swarup Surin, Atul Harsh, Harjit Kaur Conference Proceedngs Wccst 2026 World Conference on Computational Science and Technology, 2026 This paper reviews the use of transfer learning in the field of question answering and document retrieval focusing on two advanced models: T5 (Text-To-Text Transfer Transformer) and BERT(Bidirectional Encoder Representations from Transformers). Transfer learning enables pre-trained model to be fine-tuned for specific tasks offering a powerful framework for addressing complex challenges in natural language processing. The advantages of both models in extracting applicable information from documents and answering questions with high precision are reviewed. The study focus on their ability to capture semantic assess their performance across various dataset and discuss challenges faced during model fine-tuning. Understanding the models architectures, training method, and performance metrics are provided contributing to the continue development of reliable natural language processing systems for practical applications. Overall, this review will help to gain better insights into the transformer-based transfer learning methods and contribute to the further advancement of the efficient and high-quality natural language processing systems that can be used in practice.
Impact of bandwidth alignment and RF-data rate interaction in single-drive Mach-Zehnder modulator-based radio-over-fiber systems Jatinder Kaur, Malatesh Akkur, Pradeep Kumar Mishra, Vishal Thakur, Sachin Chawla, Mukesh Kumar Tripathi Journal of Optical Communications, 2026 A radio frequency (RF) signal, when transmitted through an optical fiber network after modulating the light signal with the RF signal, is known as radio over fiber or RoF. This technology can utilize a large bandwidth so that it can support more users compared to regular wireless technology. RoF is a cost-effective and flexible alternative to fulfill the high and rapidly increasing consumer and commercial demands, such as internet services, which need bandwidth. In this paper, a hybrid 10 GHz RoF system is designed, which operates at multiple data rates of 5, 10, 15, and 20 Gbps. In this system, RF signal is used to modulate the light signal using a single-drive Mach–Zehnder modulator. The signal is transmitted through fiber, and coherent detection is implemented using a mixer and a local oscillator. Performance of the system is analyzed in terms of Q-factor, BER, and SNR. At 5 and 10 Gbps, system exhibits excellent performance, and at 20 Gbps, system performs moderately, while a significant degradation is observed at 15 Gbps due to spectral overlap and filtering limitations. This paper highlights the effect of bandwidth alignment and RF–data rate interaction in RoF systems.
