A method for removing defects at high pressure and high temperature (HP/HT) or for relieving strain in a non-diamond crystal commences by providing a crystal, which contains defects, and a pressure medium. The crystal and the pressure medium are disposed in a high pressure cell and placed in a high pressure apparatus, for processing under reaction conditions of sufficiently high pressure and high temperature for a time adequate for one or more of removing defects or relieving strain in the single crystal.

A matching layer for ultrasound transducers has a gradient in impedance value from one surface to the other surface of the matching layer. The matching layer is composed of a plurality of sublayers made of composite materials and securely attached together and is disposed on the surface of the transducer element. The first sublayer adjacent to the transducer element has an impedance value less than or equal to that of the transducer element. The last sublayer adjacent to the target has an impedance value greater than or equal to that of the target. The impedance values of the sublayers decrease monotonically from the first to the last sublayer.

A light source ( ) includes a light emitting component ( ), such as a UV/blue light emitting diode or laser diode, a layer ( ) of a light scattering material ( ), and a layer ( ) of a phosphor material ( ). The phosphor material converts a portion of the light emitted by the light emitting component to light of a longer wavelength, such as yellow light. The scattering material scatters the light emitted by the light emitting component and/or the light converted by the phosphor to improve the overall uniformity of the angular distribution of the light. When combined, the converted and scattered light has a more uniform angular distribution, that is, it maintains the approximately the same color as the viewing angle is changed.
