A light emitting diode (LED) grown on a substrate doped with one or more rare earth or transition element. The dopant ions absorb some or all of the light from the LED's active layer, pumping the electrons on the dopant ion to a higher energy state. The electrons are naturally drawn to their equilibrium state and they emit light at a wavelength that depends on the type of dopant ion. The invention is particularly applicable to nitride based LEDs emitting UV light and grown on a sapphire substrate doped with chromium. The chromium ions absorb the UV light, exciting the electrons on ions to a higher energy state. When they return to their equilibrium state they emit red light and some of the red light will emit from the LED's surface. The LED can also have active layers that emit green and blue and UV light, such that the LED emits green, blue, red light and UV light which combines to create white light. Alternatively, it can have one active layer and grown on a sapphire substrate doped with Cr, Ti, and Co such that the substrate absorbs the UV light and emits blue, green, and red light. The invention is also capable of providing a tunable LED over a variety of color shades. The invention is also applicable to solid state laser having one or more active layers emitting UV light with the laser grown on a sapphire substrate doped with one or more rare earth or transition elements.

To solve problems of a conventional moving picture photographing using a high pixel density color solid-state imaging element that reflected noise intruded to a low frequency region of a high frequency video signal due to resampling is unavoidable and the effective sensitivity is remarkably deteriorated through aborted pixel signals although interleaved pixel reading represented by pixel interleaving in the vertical direction is generally employed. Pixel areas of the high pixel density color solid-state imaging element are divided into areas in units of pixel mixture, and all pixels in the same color are respectively mixed in each of the area divisions (16 to 19) to increase the pixel utilizing rate to 100%, and the spatial LPF effect of area pixel mixing remarkably suppresses the intrusion of reflected noise to the low frequency region of the high frequency video signal.
