Neutron heavy irradiation was performed on synthetic diamonds contain nitrogen atoms in isolated substitutional form (called “type Ib diamond”) and they were annealed under a pressure of 6 GPa. A large number of nitrogen B-aggregate which consist

The absorption strengths of the N3 centres in natural type-Ia and in neutronirradiated and post-annealed synthetic type-Ib diamonds have been measured under various illumination conditions. In the type-Ib diamond, an increase in absorption is observe

For type-Ib diamond, we have experimentally studied the change in the Raman spectrum with the concentration of nitrogen impurities, the fluence of neutron irradiation and $^{13}\mathrm{C}$ isotope composition, to look for phonon scattering due to the

To study the electronic states of an NV center in synthetic type-Ib diamonds, the Zeeman effect of the zero-phonon line (ZPL) in the absorption spectrum has been examined under high magnetic fields B, up to 150 T at 77 K. The absorption peak energies

This paper proposes a new architecture of the feedforward multibit DeltaSigmaAD modulator for low power application. The SQNDR (Signal to Quantization Noise and Distortion Ratio) of DeltaSigmaAD modulator is limited by the dynamic range of the input

Photochromism has been studied for irradiated type Ib diamonds which are then annealed above 1500 degrees C. This mainly involves H2 and H3 centres. When the samples are illuminated with light of wavelength shorter than 600 nm, absorption of H2 centr

Infrared absorption and electron spin resonance measurements have been performed in nitrogen-containing mixed-type diamonds under several illumination conditions. It has been observed that bulk one-phonon absorption spectra are modulated by illuminat

Near-infrared absorption lines of 2916, 4066, 4113, 4139 and 4168 cm−1 have been observed in type IIa diamond neutron irradiated and annealed at temperatures higher than 1400°C. A photochromic behaviour of these defects under various illumination
