Структурные И Оптические Характеристики Синтетических Алмазов В Нано-, Микро- И Миллиметровом Масштабе

Abstract

Synthetic diamonds are the subject of research in many different implementations. Recognition of the properties of materials with dimensions near the nanometre scale is of great importance for essential science and multiple applications. Microdiamonds synthesised by the HPHT method and nanodiamonds made by detonation were evaluated using XRD, SEM, TEM and Raman spectroscopy. UV-VIS luminescence measurements were performed and compared with each other to assess the surface defects and grain size influence on their optical properties.
