I have coated it at 300 and 350C and used Cadmium chloride and selenium dioxide as a source material. Normally the colour of the CdSe thin film will be red or reddish brown in colour. but what i got is white in colour i dont know why.
Hi Mathuri,
about your CdSe film,
what is the
1. substrate ?
2. thickness ?
I agree with Ioannis: More information are needed to have a better view of what is happening.
(additional questions)
3. deposition method ?
4. estimated roughness ?
comments:
- The last question is about scattering; is the white color a milky-white from diffusion of light? Or is it a shinny white color with high specular reflectance?
- The question about the thickness is also very important: the reddish color that your are referring to may be for films with very different thickness values.
Hello sir thanks for your immediate clarification. I have coated it on glass substrate by spray pyrolysis method and regarding roughness i didnt measured it yet. when i increase the concentration of the source material then iam getting milky white other wise its shinny white colour sometimes its look colourless.
