Is there any official naming of complex (not the basic ones) Chinese Characters in Mandarin Chinese.

For example, I know that the character 博 is pronounce in Pinyin as:

[bó][1]

But If I were to, address (the name of) this particular character, and not intending to address its pronunciation, what name should I use? (example:the letter W is pronounce as "w" as in "ˈwɔːtə(r)" for the word water in the IPA of BrE but the letter itself is named (referred to as) "double u")

Note: Please add the resources link for this. I'm at a level of a beginner so please add some pinyin in your answer so that I can read it.

Regards
