The CVD diamond UV photodetector shows more than four orders of photoresponsivity discrimination between UV and visible light. Post-treatment on as-fabricated photodetector is essential for a good response to UV light and blindness to visible light. The CVD diamond X-ray detector shows linear dependence of photocurrent on X-ray intensity and high response speed. The mapping of charge collection efficiency on the whole sensing area of a CVD diamond alpha particle detector has been obtained using ion-beam-induced charge microscopy technique. Three peaks have been observed in the charge collection spectrum.
