Photoluminescence and Electroluminescence of Eu Doped Y2O3

, 2015
In this paper, Eu doped Y2O3 nanophosphors are prepared at temperature 600oC by the combustion method. X-ray diffraction patterns confirm the formation of pure cubic phase of Y2O3.

Assessing relational values of sacred landscapes through text mining of folktales: Insights from the Ryukyu Islands, Japan

People and Nature, EarlyView.
Abstract Assessing relational values of nature through its cultural and spiritual significance is crucial for effective nature conservation. Folktales offer insights into traditional relationships between people and nature, and text mining is a powerful tool for extracting information from textual datasets.

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their
