Perhaps you should try some spelling variations:
photophysical pathways » photophysical methods (Expand search)
decrease photophysical » decrease physical (Expand search)
decreased can » decreased mean (Expand search), decreased in (Expand search), decreased and (Expand search)
in decreased » is decreased (Expand search), in deceased (Expand search), and decreased (Expand search)
can decrease » can increase (Expand search), and decrease (Expand search), to decrease (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease in decreased can decrease ) OR ( decrease of decrease photophysical pathways ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decreased can decrease ) OR ( decrease of decrease photophysical pathways ))*.
