摘要:
In a method for making a pulsed high-voltage silicon quantum dot fluorescent lamp, an excitation source is made by providing a first substrate, coating the first substrate with a buffer layer of titanium, coating the buffer layer with a catalytic layer of a material selected from a group consisting of nickel, aluminum and platinum and providing a plurality of nanometer discharging elements one the catalytic layer. An emission source is made by providing a second substrate, coating the second substrate with a transparent electrode film of titanium nitride and coating the transparent electrode film with a silicon quantum dot fluorescent film comprising silicon quantum dots. A pulsed high-voltage source is provided between the excitation source and the emission source to generate a pulsed field-effect electric field to cause the nanometer discharging elements to release electrons and accelerate the electrons to excite the silicon quantum dots to emit pulsed visible light.
摘要:
A structure is formed by putting glass plates between a luminescence generating device and an electron emitting device so that a vacuum is formed in between. After in putting a high-voltage, an electron beam is emitted from the electron emitting device using low power. In the end, silicon quantum dots in the luminescence generating device are excited to generate a white light. The present invention has a good optoelectronic transformation efficiency.

摘要:
A white light photodiode has a film layer and an ultraviolet (UV) photodiode. The film layer is made of an oxide rich in silicon; and is formed through a chemical vapor deposition. A white light can be generated by exciting the film layer with a UV light from the UV photodiode.

A carbon nanotube is prepared under a non-vacuum environment. An atmospheric pressure chemical vapor deposition (APCVD) is processed with an external high frequency source and a perpendicularly-supplied gas material source for a cold-wall heating treatment. The carbon nanotube is thus obtained with a vertically aligned arrangement at a high speed and a pure quality for production.
摘要:
A distribution layer of silicon quantum dots are fabricated. After the layer is exposed to sun light for a while, the layer absorbs energy and produces pairs of electron and hole. By limiting the movement of the electrons and their moving directions through the structure obtained, the efficiency of an optoelectronic conversion is enhanced.
摘要:
An amorphous silicon (Si) film is taken to form a metal silicide of Si—Al(aluminum) under a high temperature. Al atoms is diffused into the amorphous Si film for forming the metal silicide of Si—Al as nucleus site. Then through heating and annealing, a microcrystalline or nano-crystalline silicon thin film is obtained. The whole process is only one process and is done in only one reacting chamber.
