Dear Cansu Akyol thank you for sharing this very interesting technical question with the RG community. As a synthetic inorganic chemist I'm certainly not a proven expert in the field of photophysical studies. However, to the best of my knowledge you need an LED laser to study the photosensitizer properties of chloro aluminum phthalocyanine. You should also carefully study the relevant current literature about this topic to get an overview of what has already been done in this field. For example, please have a look at the following potentially useful articles which might help you in your analysis:

Evaluation of photodynamic treatment using aluminum phthalocyanine tetrasulfonate chloride as a photosensitizer: New approach

Article Evaluation of photodynamic treatment using aluminum phthaloc...

and

Photophysical studies of zinc phthalocyanine and chloroaluminum phthalocyanine incorporated into liposomes in the presence of additives

Article Photophysical studies of zinc phthalocyanine and chloroalumi...

Fortunately these two articles have been posted by the authors as public full texts on RG. Thus you can freely download them as pdf files. Also please see:

Chloro-aluminium phthalocyanine loaded in ultradeformable liposomes for photobiology studies on human glioblastoma

Article Chloro-aluminium phthalocyanine loaded in ultradeformable li...

This article is not yet accessible as public full text. However, all three authors have RG profiles. Thus you can easily contact one of them directly via RG and request the full text.

I hope this helps. Good luck with your work and best wishes, Frank Edelmann
