Silicon can be caused to photoluminesce in the visible by rapid anisotropic etching of bulk samples to form a porous material, Both electrochemical and ,chemical etching procedures based on an HF reagent have been developed for this purpose. Porous silicon is found to contain nanoscopic sihcon parti
